ABSTRACT:
A power supply circuit includes a power supply stabilizing circuit, a reset circuit, and a switching circuit. The power supply stabilizing circuit stabilizes a power supply voltage from a power supply and applying the voltage to a main circuit. The reset circuit outputs a reset signal to the main circuit when the power supply voltage rises. The switching circuit is connected to the power supply stabilizing circuit. The switching circuit stops supply of power to the reset circuit when the voltage applied to the main circuit becomes a value not more than a predetermined value after supply of power is interrupted.
