定電圧電源回路。 The collector and emitter of a control transistor are connected in series between the DC input terminal and the output terminal, and the collector and emitter of a drive transistor is connected between the base of the control transistor and a reference potential point, which has an emitter resistor. At the same time, the voltage obtained at the output terminal is applied as the other input of a voltage comparator to which a reference voltage for setting the output voltage is applied as one input, and the output of this comparator is applied to the base of the drive transistor. A constant voltage power supply circuit comprising a switching diode connected between the base of the drive transistor and the output terminal.
