A method for stability compensation of low-load-capacitor low-power LDO
A stability compensation method for low-load-capacitor low dropout regulator (LDO) is presented. A ldquozeropsilas frequency trackingrdquo as well as ldquonon-dominant parasitic polespsila frequency reshapingrdquo are performed to obtain nearly first order system behavior out of several quite unmanageable locations of pole-zero frequencies of uncompensated system. The LDO consumes 170 muA (including the consumption of reference circuit) over full load current range and is implemented on 0.13 mum CMOS technology.
