Abstract
A low-dropout regulator for low voltage applications includes a buffer circuit being arranged between an output terminal of an error amplifier and a control node of a pass device. The buffer circuit includes a driver having a first transistor being embodied as an NMOS transistor. The output terminal of the error amplifier is coupled to the control node of the first transistor. The control node of the pass device is coupled to an internal node of a first current path including the first transistor. The low-dropout regulator has high load capability, even if an input supply voltage is very low.
