Product Introduction

Overview

The LP2951CDM-3.3R2G is a micropower low dropout (LDO) linear voltage regulator produced by onsemi. This device is designed to maintain proper regulation with an extremely low input-to-output voltage differential. It features a very low quiescent bias current of 75 µA and is capable of supplying output currents in excess of 100 mA. The LP2951 series includes internal current and thermal limiting protection, making it ideal for battery-powered computer, consumer, and industrial equipment where extending the useful battery life is desirable.
