More Information
Summary:Provided is a voltage regulator capable of suppressing a current consumption in a non-regulation state with a simple circuit configuration. The voltage regulator includes an output transistor supplying an output voltage based on a control voltage, an error amplifier circuit supplying an amplified signal obtained by amplifying a difference between a voltage based on the output voltage and a reference voltage, a common source amplifier circuit supplying the control voltage to the output transistor based on the amplified signal, and a non-regulation state detection circuit supplying a detection signal to the common source amplifier circuit. The common source amplifier circuit includes a current control circuit including a plurality of parallel paths connecting between a control terminal of the output transistor and a power supply terminal, the plurality of parallel paths including a path to be closed in the non-regulation state and a path to be opened in the non-regulation state.
