Product Overview

The LP2951ACMX-NOPB is a high-accuracy micropower voltage regulator by Texas Instruments (TI), designed for low-power systems with extremely low quiescent current (75μA typ.) and low dropout voltage (40mV at light loads, 380mV at 100mA). Supporting programmable output voltage from 1.24V to 29V, this 8-pin SOIC package regulator integrates an error flag and logic-controlled shutdown function. Ideal for battery-powered devices, portable electronics, and industrial controls, it ensures stable output while significantly extending battery life.

Key Features
