More Information
Summary:A voltage regulator (10) includes an error amplifier (100), and the error amplifier (100) includes a differential pair (102, 103) constituted by a pair of transistors, a current adjustment circuit (120) that provides a bias current proportional to an output current supplied from an output transistor to the differential pair (102, 103), a source output circuit (107) and a sink output circuit (109) that provide a current based on a current flowing through the differential pair (102, 103) to an output terminal (3) of the error amplifier (100), and a phase compensation circuit (130) that controls a current of the sink output circuit (109) based on a current of the current adjustment circuit (120).
