Beschreibung
Zusammenfassung:	A voltage regulator includes: a comparator configured to compare a feedback voltage with a reference voltage to output an enable signal and operate based on a bias current; a pass transistor turned on according to the enable signal and configured to output an external power voltage as an output voltage; a voltage distribution circuit configured to distribute and output the output voltage to an input terminal of the comparator; and a bias current control unit configured to control an amount of the bias current supplied to the comparator based on the output voltage.
