Abstract
A low drop-out (LDO) regulator includes a power transistor, an error amplifier and a droop adjusting circuit. The power transistor regulates a driving voltage based on a gate voltage of a gate node to provide an output voltage at an output node. The error amplifier outputs the gate voltage by amplifying a voltage difference between a reference voltage and a feedback voltage proportional to the output voltage. The droop adjusting circuit is connected between the gate node and the output node, is coupled to the output voltage, and adjusts the gate voltage to compensate for a change of the output voltage based on a change of a load current which is provided to a load from the output node.
