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 voltageconditionis 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-byline to allow the
μ
P to store data.
