Well, I was thinking about this the other night, and wondered if the current limit meant that the open-loop gain decreased as the capacitive load increased, and therefore kept it stable. But then I considered that the current limit is not active all the time (only when trying to slew fast into large C loads) and so should not affect the small-signal response. So I'm not sure that Mr Al's response quite covers it.... or am I missing something?
Thanks for the interest; any other insights welcome!
