る電源供給制御回路。 A power supply transistor having an emitter-collector path inserted and connected between the power supply and the load and supplying power to the load when in a conductive state; and a power supply transistor controlling the base to supply power to the load when in an operating state. a control transistor whose emitter is connected to the power supply and whose emitter is connected to the power source and whose base is connected to the collector of the control transistor via a resistor; ,
a second transistor whose collector is connected to the base of the power supply transistor via a resistor and whose emitter is grounded, and to which a base current is supplied between the emitter and collector of the first transistor; The diode is connected between the collector of the transistor and the base of the first transistor, and transmits changes in the collector voltage of the power supply transistor to the base of the first transistor, and controls whether the control transistor is conductive or not. The operation of the power supply transistor is controlled by conduction, and the bias current of the first transistor and the second transistor is changed in response to a change in the collector voltage of the power supply transistor. A power supply control circuit characterized in that the base current is changed.
