Abstract
The present invention provides a series control type regulator which can decrease rapidly an output voltage regardless of heaviness or lightness of a load when a first transistor for controlling an output voltage is set to a state of stop of operation. When a switching circuit sets the first transistor from a state of operation to a state of stop, at the same time an output capacitor is discharged by causing to a discharge circuit connected in parallel to the output capacitor. The discharge circuit starts operating by turning on a third transistor, which turns on by a current flowing to voltage dividing resistors of a detection circuit being used as a base current. The voltage dividing resistors of the detection circuit are also used as resistors for setting a base current of the third transistor.
