Abstract
A voltage regulator includes: a first comparator for comparing a first reference voltage with a feedback voltage to generate a first comparing result accordingly; a first transistor for controlling an output voltage at an output node in response to the first comparing result; a second transistor for adjusting the output voltage at the output node in response to a control signal; a feedback block, for providing the feedback voltage according to the output voltage; and a control block, for receiving the output voltage and providing the control signal according to the output voltage.
