摘要： A voltage regulator with a low quiescent current is provided. The voltage regulator includes a pulse voltage generating unit, a first switch unit, a regulating unit and a power output unit. The pulse voltage generating unit receives an input voltage to provide an intermittent signal with a predetermined period, and output a pulse voltage according to the intermittent signal. The first switch unit is turned on according to the intermittent signal. The regulating unit converts the pulse voltage into a continuous voltage. The power output unit receives the continuous voltage to output a voltage power through a power output terminal. And, the power output unit detects an output current of the power output terminal to adjust current drive capability of the power output unit dynamically. Thus, the pulse voltage generating unit consumes power while the intermittent signal is enabled, so as to achieve the power saving effect.
