摘要：

This paper presents a low-power fully integrated 0.18 mu m CMOS Low-Dropout (LDO) Voltage Regulator for battery-operated portable devices. A single stage high-gain telescopic cascode-compensated amplifier is used to attain good static performances, while thanks to a very simple dynamic bias circuit, transient performances are significantly enhanced with no quiescent current penalty. Results validate a 1.8 V output voltage from a 3.6 V to 1.9 V battery input voltage, delivering a load current of 50 mA over a 100 pF load. The quiescent current is only 7 mu A, the line and load regulation are respectively 0.159 mV/V and 0.017 mV/mA, and settling times are lower than 4.6 mu s at full load transient.
