摘要：
Provided is a voltage regulator having a structure in which an output terminal of a first differential amplifier circuit is connected to a second differential amplifier circuit to control an output transistor by the second differential amplifier circuit. When low current consumption is required, the first differential amplifier circuit is suspended. When high-speed response is required, the first differential amplifier circuit is activated. The low-current consumption operation and the high-speed operation are switched with a minimum circuit area.
