Abstract: Disclosed embodiments provide a power supply circuit, a control method therefor and an electronic device to improve flexibility and application scenarios of a power supply. The power supply circuit includes a first voltage converter, a second voltage converter and a first low dropout regulator, where an output end of the first low dropout regulator is electrically connected to a first load end. A multiplexing module is configured to connect, based on a power-on state and a power-off state of the second voltage converter, one of an output end of the first voltage converter and an output end of the second voltage converter to the first load end through the first low dropout regulator.
