PROBLEM TO BE SOLVED: To provide a voltage regulator that suppresses the generation of excessive overshoot at an output terminal when a power source voltage is increased in a non-regulated state in spite of low current consumption.SOLUTION: The voltage regulator comprises: an overshoot limiting circuit detecting the generation of overshoot at an output voltage and limiting current of an output transistor; and a non-regulated state detection circuit detecting that the voltage regulator is in a non-regulated state on the basis of the voltage of the output terminal and current flowing through the output transistor. Operation current of the overshoot limiting circuit is controlled by a detection signal of the non-regulated state detection circuit. |
