Abstract	Ring amplification has emerged as an efficient technique to drive large capacitive loads in switched capacitor circuits. We propose circuit techniques to demonstrate the first application of a ring amplifier in a non-capacitive feedback system of a LDO. These techniques enable a simple cap-less LDO structure in 180nm CMOS that can achieve less than 700ns settling time for load transitions between 100uA-40mA with a quiescent current of 6.5uA while regulating a 1V output with a 80mV drop out voltage.
