The NCP551 series can be current boosted with a PNP transist-
or. Resistor R in conjunction with V
BE
of the PNP determines
when the pass transistor begins conducting; this circuit is not
short circuit proof. Input/Output differential voltage minimum is
increased by V
BE
of the pass resistor.
Short circuit current limit is essentially set by the V
BE
of Q2 and
R1. I
SC
= ((V
BEQ2
− ib * R2) / R1) + I
O(max)
Regulator
If a delayed turn−on is needed during power up of several volt-
ages 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
output (V
out
) is shorted to GND
.
