Abstract
A power supply circuit that accurately generates output voltages with the same regulator includes a regulator for generating a first output voltage from an input voltage. A first switch circuit, connected to the regulator, selectively outputs the first output voltage of the regulator as a second output voltage from the power supply circuit. A pre-charge circuit, connected to the regulator and the first switch circuit, generates the second output voltage from the input voltage before the first output voltage of the regulator is output as the second output voltage while controlling the first switch circuit.
