A switching regulator: first switching element and second switching element; a logic unit which outputs to the load the output voltage converted from the input voltage to the constant voltage, by causing the first switching element and the second switching element to perform a switching operation; an error amplifier which outputs first signal indicating an error between the output voltage and the first reference voltage; first comparator which inputs the first signal and second signal indicating an output voltage that is proportional to load current flowing in the load, and outputs to the logic unit control signal causing the logic unit to perform the switching operation based on the first signal and the second signal; and a correction unit which is connected to an input side of the error amplifier, and corrects an input voltage of the error amplifier to reduce the input voltage to a certain value or lower. |
