Functional Description

This device is a 5-V low-drop fixed-voltage regulator. The maximum input voltage is

45 V. It can deliver an output current of at least 180 mA. The IC is short-circuit proof and

features temperature protection that disables the circuit in the event of impermissibly

high temperatures. The watchdog function is disabled as a function of the load, so that

a controller is not interrupted during sleep mode by a watchdog reset.

Application Description

The IC regulates an input voltage

in the range 5.5 V

45 V to

qrated

= 5.0 V. In

the event of an output voltage

, a reset signal is generated. The wiring of the

reset switching threshold input enables the value of

to be reduced. The reset delay

time can be adjusted using an external capacitor. The integrated watchdog monitors the

connected active controller. If there is no positive-going edge at the watchdog input, the

reset output is set to low. The reset delay capacitor provides a wide adjustment range

for the pulse repetition time. The watchdog function is only activated if the load exceeds

8 mA. This ensures that a microcontroller is not activated during power-down and the

current drain is not increased. The IC is protected against overload and

overtemperature.
