There is provided a low drop-out regulator. The low drop-out regulator includes a reference voltage generating unit converting input power to generate a reference voltage; an amplifier comparing the reference voltage and a feedback voltage to output a gate signal; a pass transistor array unit including a first transistor and a second transistor respectively including a gate receiving the gate signal; a voltage detector detecting the feedback voltage and an output voltage by using a switching operation of the pass transistor array unit; and a controller shutting off the gate signal applied to either of the first transistor or the second transistor, according to the reference voltage and the input power. |
