DESCRIPTION
The REF30xx is a precision, low power, low voltage dropout
voltage reference family available in a tiny SOT23-3.
The REF30xx small size and low power consumption (50µA
max) make it ideal for portable and battery-powered applica-
tions. The REF30xx does not require a load capacitor.
Unloaded, the REF30xx can be operated with supplies within
1mV of output voltage. All models are specified for the wide
temperature range, –40°C to +125°C.

DISCHARGE SENSITIVITY
This integrated circuit can be damaged by ESD. Texas Instru-
ments recommends that all integrated circuits be handled with
appropriate precautions. Failure to observe proper handling
and installation procedures can cause damage.
ESD damage can range from subtle performance degradation
to complete device failure. Precision integrated circuits may be
more susceptible to damage because very small parametric
changes could cause the device not to meet its published
specifications.

THEORY OF OPERATION
The REF30xx is a series, CMOS, precision bandgap voltage
reference. Its basic topology is shown in Figure 1. The
transistors Q1 and Q2 are biased such that the current
density of Q1 is greater than that of Q2. The difference of the
two base-emitter voltages, Vbe1 – Vbe2, has a positive
temperature coefficient and is forced across resistor R1. This
voltage is gained up and added to the base-emitter voltage
of Q2, which has a negative coefficient. The resulting output
voltage is virtually independent of temperature. The curvature
of the bandgap voltage, as seen in the typical curve, “Output
Voltage vs Temperature,” is due to the slightly nonlinear
temperature coefficient of the base-emitter voltage of Q2.
The REF30xx features a low quiescent current, which is
extremely stable over changes in both temperature and
supply. The typical room temperature quiescent current is
42µA, and the maximum quiescent current over temperature
is just 59µA. Additionally, the quiescent current typically
changes less than 2.5µA over the entire supply range, as
shown in Figure 3.
Supply voltages below the specified levels can cause the
REF30xx to momentarily draw currents greater than the
typical quiescent current. Using a power supply with a fast
rising edge and low output impedance easily prevents this.

APPLICATION INFORMATION
For normal operation, the REF30xx does not require a
capacitor on the output. If a capacitive load is connected,
special care must be taken with the combination of low
equivalent series resistance (ESR) capacitors and high
capacitance. This caution is especially true for low-output
voltage devices; therefore, the REF3012 should only have a
low-ESR capacitance of 10µF or less. Figure 2 shows the
typical connections required for operation of the REF30xx. A
supply bypass capacitor of 0.47µF is always recommended.
SUPPLY VOLTAGE
The REF30xx family of references features an extremely low
dropout voltage. With the exception of the REF3012, which has
a minimum supply requirement of 1.8V, the REF30xx can be
operated with a supply of only 1mV above the output voltage in
an unloaded condition. For loaded conditions, a typical dropout
voltage versus load is shown on the cover page.
THERMAL HYSTERESIS
Thermal hysteresis for the REF30xx is defined as the change
in output voltage after operating the device at 25°C, cycling
the device through the specified temperature range, and
returning to 25°C, and can be expressed as:
VabsV V
Vppm
HYST PRE POST
NOM
=
•
(
)
–106
Where: VHYST = Calculated hysteresis
VPRE = Output voltage measured at 25°C pre-
temperature cycling
VPOST = Output voltage measured when device has
been operated at 25°C, cycled through specified
range –40°C to +125°C and returned to operation at
25°C.
TEMPERATURE DRIFT
The REF30xx is designed to exhibit minimal drift error, defined
as the change in output voltage over varying temperature.
Using the “box” method of drift measurement, the REF30xx
features a typical drift coefficient of 20ppm from 0°C to 70°C—
the primary temperature range of use for many applications.
For industrial temperature ranges of –40°C to 125°C, the
REF30xx family drift increases to a typical value of 50ppm.

SBVS032F www.ti.com
NOISE PERFORMANCE
The REF30xx generates noise less than 50µVp-p between
frequencies of 0.1Hz to 10Hz, and can be seen in the Typical
Characteristic Curve “0.1 to 10Hz Voltage Noise.” The noise
voltage of the REF30xx increases with output voltage and
operating temperature. Additional filtering may be used to
improve output noise levels, although care should be taken
to ensure the output impedance does not degrade AC
performance.
LONG TERM STABILITY
Long term stability refers to the change of the output voltage
of a reference over a period of months or years. This effect
lessens as time progresses as is apparent by the long term
stability curves. The typical drift value for the REF30xx is
24ppm from 0-1000 hours, and 15ppm from 1000-2000
hours. This parameter is characterized by measuring 30
units at regular intervals for a period of 2000 hours.
LOAD REGULATION
Load regulation is defined as the change in output voltage
due to changes in load current. Load regulation for the
REF30xx is measured using force and sense contacts as
pictured in Figure 4. The force and sense lines tied to the
contact area of the output pin reduce the impact of contact
and trace resistance, resulting in accurate measurement of
the load regulation contributed solely by the REF30xx. For
applications requiring improved load regulation, force and
sense lines should be used.

APPLICATION CIRCUITS
Negative Reference Voltage
For applications requiring a negative and positive reference
voltage, the OPA703 and REF30xx can be used to provide
a dual supply reference from a ±5V supply. Figure 5 shows
the REF3025 used to provide a ±2.5V supply reference
voltage. The low offset voltage and low drift of the OPA703
complement the low drift performance of the REF30xx to
provide an accurate solution for split-supply applications.

DATA ACQUISITION
Often data acquisition systems require stable voltage
references to maintain necessary accuracy. The REF30xx
family features stability and a wide range of voltages suitable
for most micro-controllers and data converters. Figure 6 and
Figure 7 show two basic data acquisition systems.

http://www.ti.com/productcontent for the latest availability information and additional product content details.
TBD: The Pb-Free/Green conversion plan has not been defined.
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.
