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 V_iin the range 5.5 V < V_i< 45 V to V_qrated= 5.0 V. In

the event of an output voltage V_Q< V_RT, a reset signal is generated. The wiring of the

reset switching threshold input enables the value of V_RTto 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.
