Abstract
A low dropout regulator provided includes: an impedance unit; a differential amplifier being electrically connected to the impedance unit; a current mirror unit being electrically connected to the differential amplifier; and an adaptive bias unit being electrically connected to the differential amplifier and the current mirror unit. The impedance unit is electrically connected to a negative feedback route of the differential amplifier to make a gain of the negative feedback route greater than a gain of a positive feedback route of the differential amplifier.
