Jerome,
Sorry I can't access Xplore right now, but I think one of the two papers below has the information you are looking for. As I remember there are some trade-offs in doublet compensation. Large overshoot that settles faster or less overshoot that takes a long time to settle. The trade-off between overshoot and settling time has to do with how well the zeroes compensate the poles. In the real world the compensation is never perfect. The larger the mismatch, the larger the overshoot and faster the settling.
Analysis of the settling behavior of an operational amplifier Chuang, C.T.; Solid-State Circuits, IEEE Journal of Volume 17, Issue 1, Feb 1982 Page(s):74 - 80
R. J. Apfel and P. R. Gray, “ A fast-settling monolithic operational amplifier using doublet compression techniques,” IEEE J. Solid-State Circuits, vol. Sc-9, No.6, pp332-340, Dec. 1974.
Also I think that Raul is right in that for your application, you need to design your LDO around the capacitor.
Best Regards,
Sheldon
