A switching regulator includes a ripple generating circuit that generates a ripple voltage signal having a voltage that increases when a first switch element is on and decreases when a second switch element is on, or a voltage that decreases when the first switch element is on and increases when the second switch element is on, a comparator that compares the ripple voltage signal to a reference voltage, and generates a comparison signal indicating the comparison result, and a switch element control circuit that generates, according to the comparison signal, a control signal to switch on and off of the first switch element and a control signal to switch on and off of the second switch element, and applies the control signals to the first and second switch elements, respectively, wherein the ripple generating circuit generates the ripple voltage signal based on the control signals.
