Functional Description

The TLE 4471 is a monolithic integrated very low-drop triple voltage regulator. The main

output supplies loads up to 450 mA and the additional tracked outputs can provide up to

50 mA

and

100 mA.

In

addition

the

device

includes

a

watchdog

for

microcontroller-supervision, an under-voltage reset, a power on reset and extended

enabling features. The watchdog and reset timing can be chosen independently of each

other. The TLE 4471 is available in the P-DSO-20-12 power package. It is designed to

supply microprocessor systems under the severe condition of automotive applications

and therefore it is equipped with additional protection against overload, short circuit and

overtemperature. Of course the TLE 4471 can be used in other applications as well.

The TLE 4471 operates in the temperature range of
