Abstract
A voltage regulator includes a first transistor, a second transistor, a third transistor, a feedback unit, a comparison unit, a first control unit and a second control unit. The first transistor is controlled by the feedback unit and the comparison unit, for stabilizing the voltage of the output node. When the first control unit turns on the second transistor, the voltage of the output node rises. When the first control unit turns off the second transistor, it triggers the second control unit turning on the third transistor, so the first transistor is turned on completely. Therefore, when the third transistor is turned off, the first transistor can be controlled by the feedback unit and the comparison unit for stabilizing the voltage of the output node.
