Abstract
A low drop-out (LDO) linear regulator includes: a pass transistor coupled between an input terminal and an output terminal; an error amplifier suitable for amplifying and outputting a difference between a feedback voltage corresponding to an output voltage of the output terminal and a predetermined reference voltage; a buffer including an input terminal which is coupled to an output node of the error amplifier and an output terminal which is coupled to a gate of the pass transistor; a first compensation circuit suitable for driving an equivalent resistance of the output node of the error amplifier to be in inverse proportion to a load current; and a second compensation circuit suitable for driving an equivalent resistance of an output node of the buffer to be in inverse proportion to the load current.
