摘要： A regulator includes a first amplifier, a second amplifier, a current control circuit, a first P-type metal-oxide-semiconductor transistor, a second P-type metal-oxide-semiconductor transistor, and a feedback circuit. The current control circuit includes a controller and at least one switch, and a second terminal of the first P-type metal-oxide-semiconductor transistor is coupled to a second terminal of the second P-type metal-oxide-semiconductor transistor. The regulator utilizes the controller to turn off the at least one switch during operation of the regulator in a light load mode, and the regulator utilizes the controller to turn on the at least one switch in turn when the regulator changes from the light load mode to a heavy load mode. Thus, the regulator can quickly recover a load current in the heavy load mode.
