The NCP500 series can be current boosted with a PNP transis-
tor. 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
