Abstract
According to one embodiment, a power supply circuit includes a power switch section, an error amplifier, a wiring and a reset switch section. The error amplifier has one input portion connected to the output terminal, the other input portion and an output portion. The error amplifier outputs the control potential via the output portion to make the resistance of the power switch section high so that potential applied to the one input portion is high to potential applied to the other input portion. The wiring connects a reference terminal to the other input portion. In addition, the reset switch section is configured to isolate the wiring from a baseline potential when the input terminal is supplied with a potential, and to connect the wiring to the baseline potential when the input terminal is not supplied with the potential.
