There is provided a voltage regulator capable of achieving a fast transient response upon activation without allowing an abnormal consumption current to flow. The voltage regulator of the present invention includes: a booster circuit for detecting output current from an output transistor and outputting a boost signal to a first differential amplifier circuit; a sensing transistor for sensing the output current; a first transistor for making an adjustment to enable the output current to be copied accurately; and a second differential amplifier circuit in which the output terminal is connected to the gate of the first transistor, the inverting input terminal is connected to the drain of the sensing transistor, and the non-inverting input terminal is connected to the output terminal. |
