The invention provides a voltage regulator, and the voltage regulator includes an overshoot detection circuit which detects an overshoot based on an output voltage, an overshoot suppression circuit which controls a gate voltage of an output transistor based on a detection signal of the overshoot detection circuit, a state monitoring circuit which monitors a state of the voltage regulator, a timercircuit which operates the overshoot detection circuit for a preset period in response to a signal of the state monitoring circuit, and a timer off circuit which shortens the preset period counted bythe timer circuit in response to the detection of the overshoot. 本发明提供电压调节器。该电压调节器具有：过冲检测电路，其根据输出电压，对过冲进行检测；过冲抑制电路，其根据过冲检测电路的检测信号，控制输出晶体管的栅极电压；状态监视电路，其监视电压调节器的状态；定时器电路，其接收状态监视电路的信号，使过冲检测电路进行规定的时间的动作；以及定时器断开电路，其响应于检测出过冲而缩短定时器电路进行计数的时间。
