L4953 General Description
The L4953 contains a triple voltage regulator and a power switch.
The IC 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.
