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 T_j = – 40 to 150 °C.
