engronger

Hi everybody here, our company want me to design a cap free LDO, but i still can not understand the stability of a cap free LDO when RL and Cl changed. can anybody here help me? give me some ideas or papers about this. by the way, what i must do is a NMOS pass element LDO . of course, all the information about cap free is very important for me .  thank you very much for your kindly help.

hi Kaiwei:
if you dont mind, show us the detail specification which you want to do.
in general, to make a capless LDO is not hard but due to special application.
such as PSR and line or load regulaiton , even high power.
