PROBLEM TO BE SOLVED: To provide a power supply device that suppresses drop of output voltage and outputs a predetermined setting voltage. SOLUTION: A control circuit 4 of a power supply device 100 outputs a first activation control signal S1, and controls the activation of a first low saturation regulator 2. The control circuit 4 outputs a first setting voltage control signal S3, makes the output voltage of the first low saturation regulator 2 higher than a preset setting voltage, and then controls it so as to return it to the original setting voltage. The control circuit 4 outputs a second activation control signal S2, and controls the activation of a second low saturation regulator 3. The control circuit 4 outputs a second setting voltage control signal S4, makes the output voltage of the second low saturation regulator 3 higher than a preset setting voltage, and then controls it so as to return it to the original setting voltage.
