Low-voltage linear voltage regulator suitable for memories

Abstract

In this communication a low-voltage linear voltage regulator in CMOS technology is presented. It is based on a two class-AB gain stage and, hence, does not suffer from internal slew-rate limitation when very large load capacitances are used. The linear regulator suitable for memory application was designed in a 0.35 /spl mu/m standard CMOS technology. The regulator can work with a no-regulated input voltage in the range from 1.3 V to 3 V providing a regulated voltage of 1 V with a load capacitance of 2.2 nF.
