1. An electrical power supply comprising:
- a switching voltage regulator circuit including a Schmitt trigger circuit means; and
latch means, coupled to said Schmitt trigger circuit means, for turning the switching voltage regulator off when the load current exceeds a predetermined value and which automatically resets itself when the load current goes below said predetermined value, including a pair of opposite conductivity transistors, each having a base, emitter, and collector, and a diode coupled from the collector of one of said transistors to the base of the said other transistor.

Abstract
A Schmidt trigger voltage regulator having a latching circuit at its input to disable the regulator during an overload condition and automatically resets the latching circuit when the overload condition is removed thereby allowing the regulator to function in its normal voltage regulating mode.
