Abstract

This paper describes a simple and high-performance LDO regulator designed using a $0.18{\mu}m$ CMOS process. It is designed to provide a regulated voltage for on-chip small loads instead of for off-chip heavy loads. Since the load capacitance is very small in this applications, the frequency compensation can be easily achieved without a buffer. The designed LDO drives a load current up to 15mA and dissipates only 12uA quiescent current. The line regulation is and the load regulation is for a 9mA load step. The PSRR at 10kHz is 54dB.
