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.
