Abstract
A regulator circuit includes: a voltage detection circuit that detects a magnitude of an output voltage of an output node, and outputs a feedback voltage that indicates a result of the detection; an error amplifier circuit that compares the feedback voltage with a reference voltage, and outputs a voltage that indicates a result of the comparison; an output circuit that supplies an output current to the output node according to the voltage output by the error amplifier circuit; a current detection circuit that detects a magnitude of the output current; and a current bias circuit that supplies an output bias current to the output node, and increases or decreases the output bias current based on a result of the detection of the current detection circuit.
