Low dropout: 300 mV for ADR121/ADR125
05 Figure 1.
High output current: +5 mA/−2 mA Low typical operating current: 85 μA Input range: 2.7 V to 18 V for ADR127 Temperature range: −40°C to +125°C Tiny TSOT (UJ-6) package APPLICATIONS Battery-powered instrumentation Portable medical equipment Data acquisition systems Automotive GENERAL DESCRIPTION
The ADR121/ADR125/ADR127 are a family of micropower, The ADR12x is a low dropout voltage reference, requiring only high precision, series mode, band gap references with sink and 300 mV for the ADR121/ADR125 and 1.45 V for the ADR127 source capability. The parts feature high accuracy and low above the nominal output voltage on the input to provide a power consumption in a tiny package. The ADR12x design stable output voltage. This low dropout performance, coupled includes a patented temperature-drift curvature correction with the low 85 μA operating current, makes the ADR12x ideal technique that minimizes the nonlinearities in the output for battery-powered applications. voltage vs. temperature characteristics. 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.
