A power supply circuit includes a charge pump converting voltage and a regulator controlling the converting operation of the charge pump. The charge pump stops the converting operation after a first delay time from when an output of the charge pump goes over a reference level and starts the converting operation after a second delay time longer than the first delay time from when the output of the charge pump goes below the reference level.
