Abstract

This paper presents the design of a low voltage, low dropout (LDO) regulator with two different output voltages (1V or 1.8V). The basic function of an LDO is to optimize the battery life of portable devices and to provide a constant output voltage to drive small sub-circuits. The proposed LDO was designed using 0.35/spl mu/m CMOS technology. The design is able to drive a load of up to 50mA with a maximum dropout voltage of only 200mV. A low quiescent current (at no load) of approximately 23/spl mu/A, makes this a low power design.
