Hi team,
my customer encounter large undershoot drop from 5.2V to 4.7V, I told him to increase the Rcomp ( from 2.49K to 25K),
and it did improve a bit from 5.2 to 5V, and they still want better.
but when they increase Rcomp to 47K, the signal is very noisy as shown below,
why, and is there any other way we can improve ?
BTW, they added extra output cap 65uF, but transient didn't help much..
