low voltage or no voltagecondition 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 sup-

ply capacitor that will hold enough energy for the

5V Stand-by line to allow the µP to store data.

DESCRIPTION

The L4953K contains a triple voltage regulator

and a power switch.

The IC includes a monitoring circuit to warn if a
