Abstract A switching regulator includes an input power supply connected to an input of the switching regulator; at least one input/output disconnection switch disposed between the input power supply and a device connected to an output of the switching regulator, for interrupting the supply of an energy to the device from the input power supply; and a device for limiting a rush current that flows into an output capacitor from the input power supply when the input/output disconnection switch turns on to start step-up operation.
