(1) Absolute Maximum Ratings indicate limits beyond which damage to the component may occur. Electrical specifications do not apply
when operating the device outside of its rated operating conditions.
(2) If Military/Aerospace specified devices are required, please contact the Texas Instruments Sales Office/ Distributors for availability and
specifications.
(3) The ESD rating of pins 3 and 4 for the SOT-23 package, or pins 5 and 2 for the DSBGA package, is 1 kV.
(4) The maximum allowable power dissipation is a function of the maximum junction temperature, TJ(MAX), the junction-to-ambient thermal
resistance, θJ-A, and the ambient temperature, TA. The maximum allowable power dissipation at any ambient temperture is calculated
using:
Where the value of θJ-A for the SOT-23 package is 220°C/W in a typical PC board mounting. Exceeding the maximum allowable
dissipation will cause excessive die temperature, and the regulator will go into thermal shutdown.
(5) If used in a dual-supply system where the regulator load is returned to a negative supply, the LP2985LV-N output must be diode-
clamped to ground.
(6) The output PNP structure contains a diode between the VIN to VOUT terminals that is normally reverse-biased. Reversing the polarity
from VIN to VOUT will turn on this diode, and possibly damage the device (See APPLICATION HINTS).

APPLICATION HINTS
EXTERNAL CAPACITORS
Like any low-dropout regulator, the LP2985LV-N requires external capacitors for regulator stability. These
capacitors must be correctly selected for good performance.
Input Capacitor
An input capacitor whose capacitance is ≥1 µF is required between the LP2985LV-N input and ground (the
amount of capacitance may be increased without limit).
This capacitor must be located a distance of not more than 1 cm from the input pin and returned to a clean
analog ground. Any good quality ceramic, tantalum, or film capacitor may be used at the input.
Important: Tantalum capacitors can suffer catastrophic failure due to surge current when connected to a low-
impedance source of power (like a battery or very large capacitor). If a Tantalum capacitor is used at the input, it
must be ensured by the manufacturer to have a surge current rating sufficient for the application.
There are no requirements for ESR on the input capacitor, but tolerance and temperature coefficient must be
considered when selecting the capacitor to ensure the capacitance will be ≥1 µF over the entire operating
temperature range.
Output Capacitor
The LP2985LV-N is designed specifically to work with ceramic output capacitors, utilizing circuitry which allows
the regulator to be stable across the entire range of output current with an output capacitor whose ESR is as low
as 5 mΩ. It may also be possible to use Tantalum or film capacitors at the output, but these are not as attractive
for reasons of size and cost (see CAPACITOR CHARACTERISTICS section).
The output capacitor must meet the requirement for minimum amount of capacitance and also have an ESR
(equivalent series resistance) value which is within the stable range. Curves are provided which show the stable
ESR range as a function of load current (see ESR graphs Figure 35 and Figure 36).
Figure 35. LP2985LV-N 2.2µF Stable ESR Range Figure 36. LP2985LV-N 4.7µF Stable ESR Range
Important: The output capacitor must maintain its ESR within the stable region over the full operating
temperature range of the application to assure stability.
The LP2985LV-N requires a minimum of 2.2 µF on the output (output capacitor size can be increased without
limit).
It is important to remember that capacitor tolerance and variation with temperature must be taken into
consideration when selecting an output capacitor so that the minimum required amount of output capacitance is
provided over the full operating temperature range. It should be noted that ceramic capacitors can exhibit large
changes in capacitance with temperature (see CAPACITOR CHARACTERISTICS section).
The output capacitor must be located not more than 1 cm from the output pin and returned to a clean analog
ground.

SNOS510P –NOVEMBER 1999–REVISED APRIL 2013
Noise Bypass Capacitor
Connecting a 10 nF capacitor to the Bypass pin significantly reduces noise on the regulator output. It should be
noted that the capacitor is connected directly to a high-impedance circuit in the bandgap reference.
Because this circuit has only a few microamperes flowing in it, any significant loading on this node will cause a
change in the regulated output voltage. For this reason, DC leakage current through the noise bypass capacitor
must never exceed 100 nA, and should be kept as low as possible for best output voltage accuracy.
The types of capacitors best suited for the noise bypass capacitor are ceramic and film. High-quality ceramic
capacitors with either NPO or COG dielectric typically have very low leakage. 10 nF polypropolene and
polycarbonate film capacitors are available in small surface-mount packages and typically have extremely low
leakage current.
CAPACITOR CHARACTERISTICS
The LP2985LV-N was designed to work with ceramic capacitors on the output to take advantage of the benefits
they offer: for capacitance values in the 2.2 µF to 4.7 µF range, ceramics are the least expensive and also have
the lowest ESR values (which makes them best for eliminating high-frequency noise). The ESR of a typical 2.2
µF ceramic capacitor is in the range of 10 mΩto 20 mΩ, which easily meets the ESR limits required for stability
by the LP2985LV-N.
One disadvantage of ceramic capacitors is that their capacitance can vary with temperature. Most large value
ceramic capacitors (≥2.2 µF) are manufactured with the Z5U or Y5V temperature characteristic, which results in
the capacitance dropping by more than 50% as the temperature goes from 25°C to 85°C.
This could cause problems if a 2.2 µF capacitor were used on the output since it will drop down to approximately
1 µF at high ambient temperatures (which could cause the LP2985LV-N to oscillate). If Z5U or Y5V capacitors
are used on the output, a minimum capacitance value of 4.7 µF must be observed.
A better choice for temperature coefficient in ceramic capacitors is X7R, which holds the capacitance within
±15%. Unfortunately, the larger values of capacitance are not offered by all manufacturers in the X7R dielectric.
Tantalum
Tantalum capacitors are less desirable than ceramics for use as output capacitors because they are more
expensive when comparing equivalent capacitance and voltage ratings in the 1 µF to 4.7 µF range.
Another important consideration is that Tantalum capacitors have higher ESR values than equivalent size
ceramics. This means that while it may be possible to find a Tantalum capacitor with an ESR value within the
stable range, it would have to be larger in capacitance (which means bigger and more costly) than a ceramic
capacitor with the same ESR value.
It should also be noted that the ESR of a typical Tantalum will increase about 2:1 as the temperature goes from
25°C down to −40°C, so some guard band must be allowed.
On/Off Input Operation
The LP2985LV-N is shut off by driving the ON/OFF input low, and turned on by pulling it high. If this feature is
not to be used, the ON/OFF input should be tied to VIN to keep the regulator output on at all times.
To assure proper operation, the signal source used to drive the ON/OFF input must be able to swing above and
below the specified turn-on/turn-off voltage thresholds listed in the ELECTRICAL CHARACTERISTICS(1) section
under VON/OFF. To prevent mis-operation, the turn-on (and turn-off) voltage signals applied to the ON/OFF input
must have a slew rate which is ≥40 mV/µs.
CAUTION
The regulator output voltage cannot be ensured if a slow-moving AC (or DC) signal is
applied that is in the range between the specified turn-on and turn-off voltages listed
under the electrical specification VON/OFF (see Electrical Characteristics).
(1) Exposing the DSBGA device to direct sunlight will cause misoperation. See APPLICATION HINTS for additional information.

REVERSE INPUT-OUTPUT VOLTAGE
The PNP power transistor used as the pass element in the LP2985LV-N has an inherent diode connected
between the regulator output and input. During normal operation (where the input voltage is higher than the
output) this diode is reverse-biased.
Figure 37. Normal Operation
However, if the output is pulled above the input, this diode will turn ON and current will flow into the regulator
output. In such cases, a parasitic SCR can latch which will allow a high current to flow into VIN (and out the
ground pin), which can damage the part.
In any application where the output may be pulled above the input, an external Schottky diode must be
connected from VIN to VOUT (cathode on VIN, anode on VOUT), to limit the reverse voltage across the LP2985LV-N
to 0.3V (see ABSOLUTE MAXIMUM RATINGS).
Figure 38. Operation with Schottky Diode
DSBGA MOUNTING
The DSBGA package requires specific mounting techniques which are detailed in Texas Instruments Application
Note AN-1112. Referring to the section Surface Mount Technology (SMT) Assembly Considerations, it should be
noted that the pad style which must be used with the 5-pin package is the NSMD (non-solder mask defined)
type.
For best results during assembly, alignment ordinals on the PC board may be used to facilitate placement of the
DSBGA device.
DSBGA LIGHT SENSITIVITY
Exposing the DSBGA device to direct sunlight will cause misoperation of the device. Light sources such as
Halogen lamps can also affect electrical performance if brought near to the device.
The wavelengths which have the most detrimental effect are reds and infra-reds, which means that the
fluorescent lighting used inside most buildings has very little effect on performance. A DSBGA test board was
brought to within 1 cm of a fluorescent desk lamp and the effect on the regulated output voltage was negligible,
showing a deviation of less than 0.1% from nominal.

IMPORTANT NOTICE
Texas Instruments Incorporated and its subsidiaries (TI) reserve the right to make corrections, enhancements, improvements and other
changes to its semiconductor products and services per JESD46, latest issue, and to discontinue any product or service per JESD48, latest
issue. Buyers should obtain the latest relevant information before placing orders and should verify that such information is current and
complete. All semiconductor products (also referred to herein as “components”) are sold subject to TI’s terms and conditions of sale
supplied at the time of order acknowledgment.
TI warrants performance of its components to the specifications applicable at the time of sale, in accordance with the warranty in TI’s terms
and conditions of sale of semiconductor products. Testing and other quality control techniques are used to the extent TI deems necessary
to support this warranty. Except where mandated by applicable law, testing of all parameters of each component is not necessarily
performed.
TI assumes no liability for applications assistance or the design of Buyers’ products. Buyers are responsible for their products and
applications using TI components. To minimize the risks associated with Buyers’ products and applications, Buyers should provide
adequate design and operating safeguards.
TI does not warrant or represent that any license, either express or implied, is granted under any patent right, copyright, mask work right, or
other intellectual property right relating to any combination, machine, or process in which TI components or services are used. Information
published by TI regarding third-party products or services does not constitute a license to use such products or services or a warranty or
endorsement thereof. Use of such information may require a license from a third party under the patents or other intellectual property of the
third party, or a license from TI under the patents or other intellectual property of TI.
Reproduction of significant portions of TI information in TI data books or data sheets is permissible only if reproduction is without alteration
and is accompanied by all associated warranties, conditions, limitations, and notices. TI is not responsible or liable for such altered
documentation. Information of third parties may be subject to additional restrictions.
Resale of TI components or services with statements different from or beyond the parameters stated by TI for that component or service
voids all express and any implied warranties for the associated TI component or service and is an unfair and deceptive business practice.
TI is not responsible or liable for any such statements.
Buyer acknowledges and agrees that it is solely responsible for compliance with all legal, regulatory and safety-related requirements
concerning its products, and any use of TI components in its applications, notwithstanding any applications-related information or support
that may be provided by TI. Buyer represents and agrees that it has all the necessary expertise to create and implement safeguards which
anticipate dangerous consequences of failures, monitor failures and their consequences, lessen the likelihood of failures that might cause
harm and take appropriate remedial actions. Buyer will fully indemnify TI and its representatives against any damages arising out of the use
of any TI components in safety-critical applications.
In some cases, TI components may be promoted specifically to facilitate safety-related applications. With such components, TI’s goal is to
help enable customers to design and create their own end-product solutions that meet applicable functional safety standards and
requirements. Nonetheless, such components are subject to these terms.
No TI components are authorized for use in FDA Class III (or similar life-critical medical equipment) unless authorized officers of the parties
have executed a special agreement specifically governing such use.
Only those TI components which TI has specifically designated as military grade or “enhanced plastic” are designed and intended for use in
military/aerospace applications or environments. Buyer acknowledges and agrees that any military or aerospace use of TI components
which have not been so designated is solely at the Buyer's risk, and that Buyer is solely responsible for compliance with all legal and
regulatory requirements in connection with such use.
TI has specifically designated certain components as meeting ISO/TS16949 requirements, mainly for automotive use. In any case of use of
non-designated products, TI will not be responsible for any failure to meet ISO/TS16949.
