Abstract
Provided is a voltage regulator which can achieve high-speed response and is not susceptible to a ripple. An amplifier () and an amplifier () provide push-pull output to an output transistor (). Therefore, even when an idling current is small, a sink current and a source current with respect to a gate of the output transistor () can be increased in a balanced manner. Thus, the voltage regulator can easily achieve high-speed response. In addition, even when the ripple is superimposed on an input voltage, an output voltage is not influenced by the ripple.
