The patent describes a voltage regulated power supply. It uses a small series resistance to sense load current and a circuit including a normally 'off' trigger transistor having its base connected to the load side of the series resistor for actuation to 'on' condition responsive to voltage drop in the resistor and a series switching transistor having its base connected to the output of the trigger transistor to shut off the series switching transistor in an overload condition which in turn interrupts operation of a series transistor by interrupting base current thereto. The circuit also includes a latching zener diode connected to the base of the trigger transistor to maintain its 'on' condition after overload to maintain the power supply inoperative until the fault is removed and the supply is recycled.
