Abstract

This paper presents a low-dropout regulator with quiescent current reduction. The quiescent current reduction circuit can change the Darlington Driver to the emitter follower at large dropout-voltage. The proposed LDO can output a steady voltage of -5V as the input voltage varies between -5V to -26V.The LDO with the proposed structure has been implemented in a 40V high voltage bipolar process. It is able to deliver up to 1A load current and only dissipates 1mA quiescent current at large dropout-voltage.
