Abstract: Provided is a voltage regulator capable of suppressing an overshoot with low current consumption. A comparator of an overshoot detection circuit is activated only when a power supply fluctuation occurs, and the comparator outputs a signal for reducing an overshoot occurring in an output voltage. In a steady state, the comparator of the overshoot detection circuit is turned off to prevent the current from being consumed.
