Abstract
A controlling method of a voltage regulator is provided. The voltage regulator at least includes a differential circuit and a pump high-voltage circuit which has a bias path, an output transistor and an output terminal. The controlling method includes steps of: providing at least a pre-charge path to the pump high-voltage circuit, closing the bias path and charging the output terminal with the pre-charge path when the output terminal is transient, detecting an output level of the output terminal, and closing the pre-charge path and open the bias path to bias the output transistor when the output level reaches a predetermined value.
