Patent attributes
A regulator circuit includes: a detection circuit, for outputting a feedback voltage in accordance with an output voltage; a reference voltage input section; a feedback voltage input section; an operational amplification circuit, for comparing a reference voltage and the feedback voltage and outputting a voltage as a comparison result; an output circuit, for supplying an output voltage in accordance with the output of the operational amplification circuit; a connection/disconnection circuit, for connecting or disconnecting the output terminal of the detection circuit and the feedback voltage input section; and a voltage setup circuit, for setting for the feedback voltage input section a predetermined voltage. In the standby state, the connection/disconnection circuit disconnects the output terminal of the detection circuit from the feedback voltage input section, and the voltage setup circuit sets a predetermined voltage for the feedback input section.
