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 the ADR121/ADR125 and 1.45 V for the 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 ADR121/ADR125/ADR127 are housed in the

tiny TSOT (UJ-6) package.
