L9777

Low power voltage regulator

Datasheet - production data

Features

 Operating DC supply voltage range 5.6 V to

31 V

 Low current consumption (110 μA typ @ I

= 0)

to 1 V.

 Double reset function

 Adjustable reset threshold

 External capacitor to set NMI/ reset power up

delay and watchdog frequency

 Over temperature protection

 Wide temperature range (T

J

 Short circuit proof

 Suitable for use in automotive electronics

applications and therefore equipped with

additional protection functions against over load,

short circuit and over temperature.

Of course the L9777 can also be used in other

applications where a regulated voltage is

required.
