Abstract
A voltage regulator includes an error amplifier which receives a feedback voltage and a reference voltage and thereby controls a gate voltage of an output transistor, a non-regulation detection circuit having a differential amplifier circuit operating on a current corresponding to an output current of the output transistor, and an overshoot suppression circuit having an overshoot detection circuit which enables an overshoot detection by a signal indicating the detection of non-regulation state from the non-regulation detection circuit.
