Abstract
A regulator circuit has a first non-operating state, a second non-operating state, and an operating state. The regulator circuit includes: a detection circuit that detects a magnitude of an output voltage of the regulator circuit, and outputs a feedback voltage that indicates a result of the detection to a feedback node; an operational amplifier circuit that compares the voltage of the feedback node with a reference voltage, and outputs a voltage that indicates a result of the comparison; and an output circuit that generates the output voltage according to the voltage output from the operational amplifier circuit. A state of the feedback node is different between the first non-operating state and the second non-operating state, and a transition time required to switch from the second non-operating state to the operating state is shorter than a transition time required to switch from the first non-operating state to the operating state.
