A switching regulator configured to convert an input voltage input to an input terminal into a predetermined constant voltage by switching with at least two elements including a pair of switching elements or a switching element and a rectifying element, and output the converted voltage as an output voltage from an output terminal includes a comparison unit configured to compare a signal showing an oscillating frequency of the switching regulator with a signal showing a constant frequency, and a driver configured to delay a pulse signal generated by feeding-back a control signal and an output signal of the switching regulator according to the comparison result by the comparison unit with a predetermined time, and switch the input voltage by using the at least two elements based on the pulse signal after the delay.
