Abstract
A Low Dropout Regulator (LDO) with Less Quiescent Current in the Dropout Region is described, including an error amplifier configured to compare a reference voltage to an LDO output voltage across a resistive divider, a current mirror configured to mirror a first output of the error amplifier to a first and second output of the current mirror, and a comparator configured to compare the LDO output voltage to a second output of the error amplifier, which has been compared to the second output of the current mirror, and configured to output a control voltage to the error amplifier, where a low quiescent current is maintained when an LDO input voltage is near or less than the LDO output voltage.
