Abstract
The disclosure provides a voltage generator including a first voltage regulator which provides an output voltage to an output terminal according to a reference voltage; a second voltage regulator which determines whether to operate in an enable mode or a disable mode according to an enable signal and provides the output voltage to the output terminal according to the reference voltage when operating in the enable mode; an initial voltage generator which sets a feedback voltage of the second voltage regulator to be an initial voltage value close to the reference voltage when the enable signal switches the second voltage regulator from the disable mode to the enable mode, such that the feedback voltage of the second voltage regulator is able to be locked to the reference voltage fast, and a settling time and an overshoot/undershoot of the output voltage are reduced.
