L4953K

The L4953K contains a triple voltage regulator and a power switch.

The IC L4953K includes a monitoring circuit to warn if a low voltage or no voltage condition is occuring. In stand-by output is active as long as possible even when in thermal shutdown or any other fault conditions.

The STCAP pin allows the use of a reserve supply capacitor that will hold enough energy for the 5V Stand-by line to allow the mP to store data.
