多出力直流電源装置。 In a multi-output DC power supply device comprising a plurality of voltage regulators that stabilize and output an unstable DC voltage, a voltage detection circuit generates a signal when it is detected that the unstable DC voltage has reached a predetermined tolerance range. a first voltage regulator that is activated by this signal and supplies a first DC output voltage to the load device; and a load device that is activated after a certain delay time has elapsed after detecting the rise of the first DC output voltage. and a second voltage regulator that supplies a second DC output voltage to the second voltage regulator. The operation of the first voltage regulator is stopped, the supply of the second DC output voltage is stopped, the fall of the second DC output voltage is detected, and after a certain delay time has elapsed, the operation of the first voltage regulator is stopped, and the second DC output voltage is stopped. A multi-output DC power supply device equipped with a sequence for stopping the supply of a DC output voltage.
