Product Introduction

Overview

The REF195GPZ is a precision micropower, low dropout voltage reference from Analog Devices Inc. This three-terminal voltage reference is designed to provide a precise and stable output voltage. The REF19x series, which includes the REF195GPZ, utilizes a patented temperature drift curvature correction circuit and laser trimming of highly stable, thin-film resistors to achieve a very low temperature coefficient and high initial accuracy. These devices are suitable for applications requiring low power consumption and high stability over a wide temperature range.
