LP2951 Description

Short technical summary and product information.

The Texas Instruments LP2951 is a micropower voltage regulator designed for low input-to-output voltage differentials. It can supply output currents in excess of 100 mA and features internal current and thermal limiting protection.

This regulator is suitable for battery-powered applications due to its low quiescent bias current of 75 nA. The LP2951 offers an adjustable output voltage range from 1.25 V to 29 V, with preset options of 3.0 V, 3.3 V, and 5.0 V. It also includes an error output for out-of-regulation signaling and a shutdown input for control.

The LP2951 is available in several package types, including SOIC-8, DPAK, TO-92, and Micro8 surface mount packages. Its low dropout characteristic and low quiescent current make it ideal for extending battery life in consumer and industrial equipment.
