Abstract

Provided is a voltage regulator having improved transient response characteristics even when a load current is switched from a light load to a heavy load. The voltage regulator includes, to a gate of a detection transistor constituting an output current detection circuit: a resistive element for interrupting the gate of the detection transistor from an output terminal of a differential amplifier circuit in an AC manner; and a capacitive element connected to an output terminal of the voltage regulator in an AC manner.
