LP2951A

150mA Adjustable

Voltage Regulator

POWER MANAGEMENT

Description

Features

The LP2951A is an improved version of the LP2951 and

features tighter tolerance on the output voltage and

reference voltage specifications. Both the LP2951 and

LP2951A feature 150mA output current capability.

u Guaranteed 150mA current

u Adjustable output voltage - 1.24V to 29V

u Accurate 5V output @ 150mA

u Low dropout voltage - 350 to 400mV @ 150mA

u Regulator or reference functions

u Direct replacement for LP2951AC, MIC2951-02,

AS2951AC

The LP2951 series of low power voltage regulators have

low quiescent current and low dropout voltage. The

quiescent current increases minimally during dropout

conditions thereby extending battery life.

u Full industrial temperature range

u SO-8 package

Available in the 8 lead SOIC package, the LP2951 series

includes features such as shutdown and low output

voltage detect (typically due to low battery conditions).

This function may also be used as a power on reset

function when triggered by CMOS or TTL inputs.

Applications

u Microcontroller supplies

u Linear regulators

u Adjustable Supplies

u Switching power supplies - post-regulation

u Portable modems

u Battery powered systems

u Cellular telephones

The circuit can be used as a fixed voltage 5 volt regulator

or adjusted between 1.24 volts and 29 volts using

external resistor pairs.
