DESCRIPTION
The REF31xx is a family of precision, low power, low dropout,
series voltage references available in the tiny SOT23-3 pack-
age.
The REF31xx’s small size and low power consumption
(100µA typ) make it ideal for portable and battery-powered
applications. The REF31xx does not require a load capacitor,
but is stable with any capacitive load and can sink/source up
to 10mA of output current.
Unloaded, the REF31xx can be operated on supplies down
to 5mV above the output voltage. All models are specified for
the wide temperature range of –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 REF31xx is a family of series, CMOS, precision bandgap
voltage references. The basic bandgap topology is shown in
Figure 1. 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 temperature coefficient. The
resulting output voltage is virtually independent of temperature.
100µA, and the maximum quiescent current over temperature
is just 135µA. The quiescent current typically changes less
than 2µA over the entire supply range, as shown in Figure 3.

APPLICATION INFORMATION
The REF31xx does not require a load capacitor and is stable
with any capacitive load. Figure 2 shows typical connections
required for operation of the REF31xx. A supply bypass
capacitor of 0.47µF is recommended.
SUPPLY VOLTAGE
The REF31xx family of references features an extremely low
dropout voltage. With the exception of the REF3112, which
has a minimum supply requirement of 1.8V, these references
can be operated with a supply of only 5mV above the output
voltage in an unloaded condition. For loaded conditions, a
typical dropout voltage versus load is shown in the typical
curves.
The REF31xx features a low quiescent current, which is
extremely stable over changes in both temperature and
supply. The typical room temperature quiescent current is
Supply voltages below the specified levels can cause the
REF31xx to momentarily draw currents greater than the
typical quiescent current. This can be prevented by using a
power supply with a fast rising edge and low output impedance.
THERMAL HYSTERESIS
Thermal hysteresis for the REF31xx 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. It can be expressed as:
VabsV V
Vppm
HYST PRE POST
NOM
=
(
)
10
6
Where: VHYST = Thermal hysteresis
VPRE = Output voltage measured at 25°C pre-
temperature cycling
VPOST = Output voltage measured after the device
has been cycled through the specified temperature
range of 40°C to +125°C and returned to 25°C.
TEMPERATURE DRIFT
The REF31xx is designed to exhibit minimal drift error, defined
as the change in output voltage over varying temperature. The
drift is calculated using the box method which is described by
the following equation:
VV
V TemperatureRange ppm
OUTMAX OUTMIN
OUT
106
The REF31xx features a typical drift coefficient of 5ppm from
0°C to 70°Cthe primary temperature range for many
applications. For the industrial temperature range of 40°C to
125°C, the REF31xx family drift increases to a typical value of
10ppm.

NOISE PERFORMANCE
Typical 0.1Hz to 10Hz voltage noise can be seen in the
Typical Characteristic Curve,
0.1 to 10Hz Voltage Noise
. The
noise voltage of the REF31xx 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 the
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 shown by the long-term
stability curves. The typical drift value for the REF31xx is
70ppm from 0-1000 hours. This parameter is characterized
by measuring 30 units at regular intervals for a period of 1000
hours.
LOAD REGULATION
Load regulation is defined as the change in output voltage
due to changes in load current. The load regulation of the
REF31xx is measured using force and sense contacts as
pictured in Figure 4. The force and sense lines reduce the
impact of contact and trace resistance, resulting in accurate
measurement of the load regulation contributed solely by the
REF31xx. For applications requiring improved load regula-
tion, force and sense lines should be used.

APPLICATION CIRCUITS
Negative Reference Voltage
For applications requiring a negative and positive reference
voltage, the REF31xx and OPA703 can be used to provide
a dual supply reference from a ±5V supply. Figure 5 shows
the REF3125 used to provide a ±2.5V supply reference
voltage. The low drift performance of the REF31xx
complement the low offset voltage and low drift of the
OPA703 to provide an accurate solution for split-supply
applications.

DATA ACQUISITION
Data acquisition systems often require stable voltage
references to maintain accuracy. The REF31xx family features
stability and a wide range of voltages suitable for most micro-
controllers and data converters. Figure 6, Figure 7, and
Figure 8 show basic data acquisition systems.

(2) Eco Plan - The planned eco-friendly classification: Pb-Free (RoHS), Pb-Free (RoHS Exempt), or Green (RoHS & no Sb/Br) - please check
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.
