装置。[Claims for Utility Model Registration] Transistor-stabilized DC that supplies a regulated voltage to the load by controlling switching or controlling the resistance of a main control transistor connected directly between a DC power source and a load. In the power supply device, a voltage comparator detects an overload state by comparing a detection voltage detected from a terminal of the load with a reference voltage indicating an overload state of the load; and an emitter and a base of the main control transistor. an off control transistor connected directly or indirectly between the comparator and turned on in response to the overload detection output of the comparator to control the main control transistor off. DC power supply.
