を特徴とするスイッチングレギュレータ。A switching power supply supplies a constant DC voltage to a load by controlling a control transistor on and off using pulses output from a pulse generator, and an error amplifier that compares the load voltage with a reference voltage. a remote sensing circuit that controls the control transistor by applying an error signal containing a voltage drop due to impedance of a line connecting the switching power supply and the load to a pulse generator of the switching power supply; A light-emitting element is provided on the side and converts the error signal output from the error amplifier into an optical signal, and the switching power supply receives the optical signal from the light-emitting element and supplies it as an electric signal to the pulse generator. 1. A switching regulator comprising: a light emitting element and a light receiving element; and an optical fiber cable connecting the light emitting element and the light receiving element.
