Title: about local LDO design
Post by lhlbluesky_lhl on Sep 15^th, 2012, 3:55am

i want to design a local LDO (with internal-chip CL)for pre-regulator for my one sub-module, the loading current is 20uA or so. then, what structure can i use? if i use miller two-stage opamp, can it be OK? and what value of CL should i use? 1pF can be OK? is there any suggestion? and what aspects should i consider in my LDO design?

thanks all.
