The NCP551 series can be current boosted with a PNP transist-
or. Resistor R in conjunction with V
when the pass transistor begins conducting; this circuit is not
short circuit proof. Input/Output differential voltage minimum is
increased by V
If a delayed turn−on is needed during power up of several
voltages then the above schematic can be used. Resistor R,
and capacitor C, will delay the turn−on of the bottom regulator.

A regulated output can be achieved with input voltages that
exceed the 12 V maximum rating of the NCP551 series with
the addition of a simple pre−regulator circuit. Care must be
taken to prevent Q1 from overheating when the regulated
