Abstract

See full text

A regulator circuit includes an output controlling transistor and a controller circuit. The output controlling transistor is connected between a voltage input terminal and an output terminal. The controller circuit includes an error amplifier circuit which controls the output controlling transistor according to an output feedback voltage. The error amplifier circuit includes a differential input stage, an output stage and a current increasing/decreasing circuit. The differential input stage includes input transistors and a current source. The output stage includes a current source and a transistor connected in series with the current source and amplifies a potential at one output node of the differential input stage. The current increasing/decreasing circuit includes an element having a temperature characteristic, and increases or decreases a current of the differential input stage or the current of the output stage according to the temperature characteristic.
