。In a switching regulator that positively feeds current back to the base of an output transistor and is equipped with a drive transistor that drives this output transistor, a protective resistor is installed between the output part of the output transistor and the base of the drive transistor. By providing the base current of the output transistor to the base of the drive transistor via the protective resistor when a base current of a predetermined value or higher is applied to the base of the output transistor, the base current is passed through the drive transistor. A switching regulator characterized in that it is bypassed.
