<p>PROBLEM TO BE SOLVED: To provide a low drop-out regulator.SOLUTION: The low drop-out regulator includes: a reference voltage generating unit which converts input power to generate a reference voltage; an amplifier which compares 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 gates applied with the gate signal; a voltage detector which detects the feedback voltage and an output voltage by a switching operation of the pass transistor array unit; and a controller which shuts off the gate signal applied to either of the first transistor or the second transistor, according to the reference voltage and the input power.</p> |
