摘要
A differential amplifier circuit, a voltage regulator using the differential amplifier circuit, and a method for controlling the differential amplifier circuit. The circuit includes a differential pair having a plurality of transistors, a first bias current generator circuit part to generate a first bias current to the differential pair, and a first bias current control circuit part to control a supply of the first bias current to the differential pair in response to a switching signal from outside, wherein the first bias current generator circuit part changes a current value of the first bias current in response to the switching signal.
