装置。[Claims for Utility Model Registration] A transistor-stabilized DC power supply that controls the switching or resistance of a main control transistor connected in series between a DC power supply and a load to supply a regulated output voltage to the load. The apparatus includes: a voltage comparator having one input terminal, another input terminal, and a comparison output terminal; and an output voltage detection circuit connected between one input terminal of the comparator and the satin of the load. and a reference voltage source that supplies a reference voltage indicative of an overload condition of the load to the other input terminal of the comparator, - a voltage at the one input terminal of the comparator that an off control transistor that substantially cuts off a base current of the main control transistor to control the main control transistor to turn off in response to a comparison output indicating that the voltage has become equal to or less than the voltage of the input terminal; a load on/off control circuit having a switch that is operated when stopping the supply, and making the one input terminal of the comparator the same as the voltage state of the overload state by operating the switch; A transistor-stabilized DC power supply device characterized by:
