LINEAR INTEGRATED CIRCUIT

1

QW-R102-014,A

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.

FEATURES

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

*Extremely low quiescent current in standby mode.

*High precision standby output voltage 5V±1%

*Output current capability up to 100mA.

*Very low dropout voltage less than 0.5V.

*Reset circuit sensing the output voltage

*Programmable reset pulse delay with external capacitor

*Voltage sense comparator.

*Thermal shutdown and short circuit protections.
