特徴とする電源回路。A first transistor that supplies the current of the first DC power source to the load via the collector-emitter, a second transistor that controls the base current of the first transistor and whose emitter is grounded, and a second DC low a third transistor that supplies the current of the voltage power supply to another load via the collector-emitter; a fourth transistor that controls the base current of the third transistor and whose emitter is grounded; a fifth transistor connected via a diode forward connected to a low voltage power supply, a base connected to the output side of the third transistor and an emitter connected to the collector of the fourth transistor; 4,
When the third transistor is off and the fifth transistor is off, a current is supplied from the anode side of the diode to the base of the second transistor to turn on the second transistor. 1 transistor is turned on, a signal is applied to the base of the fourth transistor to turn the fourth transistor on, and then a third transistor is turned on and a fifth transistor is turned on to turn on the diode. A power supply circuit characterized in that after a cathode side is set to a ground potential, the second transistor is turned on and off and the first transistor is turned on and off depending on the level of a signal applied to the base of the second transistor.
