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.
