To obtain a switching regulator which, when a load suddenly decreases, suppresses overshoot of output voltage without oscillating the output voltage is provided, even if being a current mode switching regulator, the present invention provides a semiconductor device for a switching regulator for converting input direct current voltage input from a direct current power supply to set direct current output voltage and outputting the output voltage from an output terminal, including: an overvoltage protection circuit for: comparing a target voltage with the output voltage at the output terminal; and making the output terminal in a discharge state when the output voltage exceeds the target voltage.
