description
The UC382 is a low-dropout-linear regulator providing a quick response to fast load changes. Combined with
its precision onboard reference, the UC382 excels at driving GTL and BTL buses. Due to its fast response to
load transients, the total capacitance required to decouple the regulator’s output can be significantly decreased
when compared to standard LDO linear regulators.
Dropout voltage (VIN to VOUT) is only 450 mV maximum at 100°C and 350 mV typical at 3-A load.
The onboard bandgap reference is stable with temperature and scaled for a 1.2-V input to the internal-power
amplifier. The UC382 is available in fixed-output voltages of 1.5 V, 2.1 V, or 2.5 V. The output voltage of the
adjustable version can be set with two external resistors. If the external resistors are omitted, the output voltage
defaults to 1.2 V.

pin descriptions
ADJ: In the adjustable version, the user programs the output voltage with two external resistors. The resistors
should be 0.1% for high accuracy. The output amplifier is configured as a non-inverting-operational amplifier.
The resistors should meet the criteria of R3 || R4 < 100 Ω. Connect ADJ to VOUT for an output voltage of 1.2 V.
Note that the point at which the feedback network is connected to the output is the Kelvin sense point. For -1,
-2, and -3 versions, ADJ pin is tied to VOUT to obtain specified output voltage.
GND: For accurate results, the GND pin should be referenced to the load ground.
VB: Supplies power to all circuits of the regulator except the collector of the output-power transistor. The 2-V
headroom from VB to VOUT allows the use of a Darlington output stage for inherently-low-output impedance
and fast response. (Dropout is derated for junction temperatures below 0°C.)
VIN: Supplies the current to the collector of the output-power transistor only. The dropout (VIN−VOUT) is under
100 mV for light loads; maximum dropout is 450 mV at 3 A for TJ = 0°C to 100°C. (Dropout is derated for junction
temperatures over 100°C.) At full load, the majority of the VB current is going to the load.
VOUT: This pin should be connected to the load via a low impedance path. Avoid connectors which add
significant inductance and resistance. Note that even though a Kelvin sense is available through a 5-pin
package, care must be taken since voltage drops along wire traces add to the dropout voltage.

APPLICATION INFORMATION
The UC382 is easy to use. The adjustable version requires two 0.1% resistors to set the output voltage. The
fixed versions of the UC382 require no external resistors. All versions of the UC382 require decoupling
capacitors on the input and output. In a typical application, VB and VIN are driven from switching power supplies
which may have large filter capacitors at their outputs. If the UC382 is further than 12 inches from the power
supply, it is recommended to add local decoupling as close as possible to the linear regulator.
Decouple the output of the UC382 with at least 100 µF of high-quality tantalum or Sanyo OSCON capacitors
close to the VOUT pin for maximum stability. Many applications involving Ultra-Fast GTL or BTL applications
require additional capacitance close to the load. The exact amount will vary according to speed and magnitude
of the load transients and the tolerance allowed for transients on VOUT. When specifying the decoupling
capacitors, the series resistance of the capacitor bank is an important factor in its ability to filter load transients.
The UC382 allows for Kelvin sensing the voltage at the load. This improves regulation performance and
eliminates the voltage drops due to wire-trace resistance. This voltage drop must be added to the headroom
(VIN to VOUT and VB to VOUT). The dropout of 450 mV is measured at the pins and does not include additional
drops due to trace resistance. The minimum load current is 10 mA.
Two or more UC382’s may be used in parallel. While stable, this arrangement does degrade the transient
response.

Pb-Free (RoHS): TI's terms "Lead-Free" or "Pb-Free" mean semiconductor products that are compatible with the current RoHS requirements for all 6 substances, including the requirement that
lead not exceed 0.1% by weight in homogeneous materials. Where designed to be soldered at high temperatures, TI Pb-Free products are suitable for use in specified lead-free processes.
Pb-Free (RoHS Exempt): This component has a RoHS exemption for either 1) lead-based flip-chip solder bumps used between the die and package, or 2) lead-based die adhesive used between
the die and leadframe. The component is otherwise considered Pb-Free (RoHS compatible) as defined above.
Green (RoHS & no Sb/Br): TI defines "Green" to mean Pb-Free (RoHS compatible), and free of Bromine (Br) and Antimony (Sb) based flame retardants (Br or Sb do not exceed 0.1% by weight
in homogeneous material)
(3) MSL, Peak Temp. -- The Moisture Sensitivity Level rating according to the JEDEC industry standard classifications, and peak solder temperature.

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 which meet ISO/TS16949 requirements, mainly for automotive use. Components which
have not been so designated are neither designed nor intended for automotive use; and TI will not be responsible for any failure of such
components to meet such requirements.
