A voltage change detecting circuit part amplifies an output signal of a differential amplifying circuit so that a slew rate thereof may be larger than that of a control signal output from a first error amplifying circuit to an output transistor, responding to change of an output voltage output from an output terminal quicker than a control signal output from the first error amplifying circuit to a first transistor, and causing a discharging circuit part to carry out discharging operation.
