Product Introduction

Overview

The REF195ESZ, produced by Analog Devices Inc., is a 5.0V precision micropower, low dropout, low voltage reference integrated circuit (IC). This device is part of the REF19x series, which utilizes a patented temperature drift curvature correction circuit and laser trimming of highly stable, thin-film resistors. This design ensures a very low temperature coefficient and high initial accuracy.

The REF195ESZ operates from supplies as low as 100 mV above the output voltage, consuming less than 45 μA of supply current. It also features a sleep mode, where the output is turned off and the supply current is reduced to less than 15 μA by applying a low TTL or CMOS level to the SLEEP pin.
