Abstract
A low-drop-output type voltage regulator may include an error amplifier providing a gate signal depending on a voltage difference between a reference voltage and a feedback voltage, a semiconductor switch adjusting a current between an input terminal receiving a battery voltage and a ground, in response to the gate signal, a feedback circuit dividing and detecting a detection voltage in a detection node between the semiconductor switch and the ground and providing the feedback voltage, a voltage sensor sensing the battery voltage, and a feedback voltage controller adjusting a level of the feedback voltage depending on the sensed battery voltage.
