UTC L2949E

LINEAR INTEGRATED CIRCUIT

MULTIFUNCTION VERY LOW

DROP VOLTAGE REGULATOR

DESCRIPTION

The UTC L2949E is a monolithic integrated 5V voltage

regulator with a very low dropout output and additonal

functions as power-on reset and input voltage sense.It is

designed for supplying the microcomputer controlled

systems especially in automotive applications.

DIP-8

SOP-8

FEATURES

*Operating dc supply voltage range 5V to 28V.
