L9777

Low power voltage regulator

Features

■ Operating DC supply voltage range 5.6 V to

31 V

■

Low current consumption (110 µA typ @ I_out= 0)

■ High precision output voltage (2 %)

■ Low dropout voltage

PowerSSO-12 (exposed DIE Pad)

■ VDD tracking regulator switchable on/off by

VDD_EN pin

■ Reset circuit sensing the output voltage down

Description

to 1 V.

The L9777 is a monolithic integrated low drop

regulator which can supply up to 200 mA,

available in the PowerSSO-12 package.

■ Double reset function

■ Adjustable reset threshold

■ External capacitor to set NMI/ reset power up

It is designed to supply microprocessor systems

under severe conditions of automotive

delay and watchdog frequency

■ Over temperature protection

applications and therefore equipped with

additional protection functions against over load,

short circuit and over temperature.

■ Wide temperature range (T_J= -40 °C to 150 °C)

■ Short circuit proof

Of course the L9777 can also be used in other

applications where a regulated voltage is

required.

■ Suitable for use in automotive electronics
