Abstract
A voltage regulator includes an error amplifier which receives a feedback voltage and a reference voltage, an amplifier circuit which receives an output voltage of the error amplifier and controls a gate of an output transistor by a first output voltage, and a non-regulation detection circuit which detects a non-regulation state of the voltage regulator based on a second output voltage of the amplifier circuit. The amplifier circuit includes a first transistor receiving the output voltage of the error amplifier at a gate of the first transistor, and a second transistor connected to a drain of the first transistor, and provides the second output voltage based on a gate-source voltage of the second transistor.
