Product Introduction

Overview

The LP2950ACZ-3.3 is a low dropout (LDO) linear voltage regulator produced by onsemi. This device is designed to provide a stable 3.3V output voltage with a maximum output current of 100mA. It is particularly suited for battery-powered devices, consumer electronics, and industrial equipment where extending the useful battery life is crucial. The regulator features a very low quiescent bias current of 75µA and an extremely low input-to-output voltage differential, making it ideal for applications requiring efficient power management.
