電源装置。 An error in which a control transistor is connected in series between an unregulated power supply circuit and a load, and the control transistor is controlled so as to detect fluctuations in the output voltage of the control transistor and stabilize the output voltage. A detection circuit is connected to the base circuit of the control transistor, an auxiliary power supply circuit is provided that generates an auxiliary power supply with a voltage higher than the output voltage of the control transistor, and the output terminal of the auxiliary power supply circuit is connected to the base circuit of the control transistor. The unregulated power supply is connected to the base of the control transistor and the input terminal of the filter circuit is connected to the unregulated power supply through a unidirectional element that becomes conductive when the output voltage of the unregulated power supply circuit becomes less than a predetermined value. Connect to the output terminal of the circuit,
A regulated power supply characterized in that it is configured to perform stable operation when the output voltage from the unregulated power supply circuit is large, and perform ripple removal operation when the output voltage from the unregulated power supply circuit becomes low. Device.
