GENERAL DESCRIPTION
The ADR121/ADR125/ADR127 are a family of micropower,
high precision, series mode, band gap references with sink and
source capability. The parts feature high accuracy and low
power consumption in a tiny package. The ADR12x design
includes a patented temperature drift curvature correction
technique that minimizes the nonlinearities in the output
voltage vs. temperature characteristics.

The ADR12x is a low dropout voltage reference, requiring only
300 mV for ADR121/ADR125 and 1.45 V for ADR127 above
the nominal output voltage on the input to provide a stable
output voltage. This low dropout performance coupled with the
low 85 μA operating current makes the ADR12x ideal for
battery-powered applications.
Available in an extended industrial temperature range of −40°C
to +125°C, the ADR12x is housed in the tiny TSOT (UJ-6)
package.

Stresses above those listed under Absolute Maximum Ratings
may cause permanent damage to the device. This is a stress
rating only; functional operation of the device at these or any
other conditions above those indicated in the operational
section of this specification is not implied. Exposure to absolute
maximum rating conditions for extended periods may affect
device reliability.
THERMAL RESISTANCE
θJA is specified for the worst-case conditions, that is, a device
soldered in a circuit board for surface-mount packages.

ESD CAUTION
ESD (electrostatic discharge) sensitive device. Electrostatic charges as high as 4000 V readily accumulate on
the human body and test equipment and can discharge without detection. Although this product features
proprietary ESD protection circuitry, permanent damage may occur on devices subjected to high energy
electrostatic discharges. Therefore, proper ESD precautions are recommended to avoid performance
degradation or loss of functionality.
