Abstract

A voltage regulator includes an error amplifier, and the error amplifier includes a differential pair constituted by a pair of transistors, a current adjustment circuit that provides a bias current proportional to an output current supplied from an output transistor to the differential pair, a source output circuit and a sink output circuit that provide a current based on a current flowing through the differential pair to an output terminal of the error amplifier, and a phase compensation circuit that controls a current of the sink output circuit based on a current of the current adjustment circuit.
