Abstract
A power supply circuit including an input terminal, an output terminal, a power output circuit, and a mode selection circuit. In the power supply circuit, the mode selection circuit is configured to supply a signal indicating whether the power output circuit is operated as a charge pump-type power output circuit or a series regulator-type power output circuit, and a voltage applied from the input terminal is stepped up or down by the power output circuit and then provided to the output terminal.
