摘要：

A CMOS low-dropout regulator (LDO) with 3.3 V output voltage and 100 mA output current for system-on-chip applications is presented. The proposed LDO is independent of off-chip capacitor, thus the board space and external pins are reduced. By utilizing dynamic slew-rate enhancement (SRE) circuit and nested Miller compensation (NMC) on LDO structure, the proposed LIDO provides high stability during line and load regulation without off-chip load capacitor. The overshot voltage has been limited within 550 mV and settling time is less than 50 mu s when load current reducing from 100 mA to I mA. By using 30 nA reference current, the quiescent current is 3.3 mu A. The experiment results agree with the simulation results. The proposed design is implemented by CSMC 0.5 mu m mixed-signal process.
