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.
