A voltage regulator according to an embodiment of the present invention outputs an enable signal by comparing a reference voltage and a feedback voltage, and includes: a comparator which operates based on a bias current supplied by a bias current source; a pass transistor which outputs an external power voltage, which is turned on according to the enable signal, into an output voltage; a voltage division circuit which distributes an output voltage and outputs the same to an input terminal of the comparator as a feedback voltage; and a bias current adjustment unit which is configured to control the amount of the bias current supplied to the comparator based on the output voltage. |
