ADR361AUJZ-R2

Overview

The ADR361AUJZ-R2 is a precision band gap voltage reference providing a nominal 2.5 V output in a compact TSOT-5 package. It operates with a supply voltage range of 2.8 V to 15 V and draws a maximum quiescent current of 190 µA. The device features an initial accuracy of ±6 mV (±0.24%) and a temperature coefficient of 25 ppm/°C. It supports sourcing up to 5 mA and sinking up to 1 mA, with a low dropout voltage of 300 mV. Output noise is specified at 8.25 µV p-p from 0.1 Hz to 10 Hz.

Feature Summary
