Power supply circuit and electronic device

An electronic device comprising:

• a power supply circuit;
• and
• a rechargeable battery connected to an output terminal of the power supply circuit
• the power supply circuit including:
• a power switch section connected between an input terminal and an output terminal and configured to vary resistance in response to an inputted control potential;
• an error amplifier having one input portion connected to the output terminal, another input portion and an output portion, the error amplifier outputting 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 another input portion;
• a wiring connecting the another input portion to a reference terminal;
• and
• a reset switch section configured to disconnect 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.
