Is a OPA445 AC stable with 100% Cap feedback at HF? - Click HERE for Original Thread

Hello,
,
1, The subject title is self explanatory - it would if possible, allow very ESR caps on the output without affecting phase stability margins so much.
2, Is there anyway of increasing the Zout of a opamp but without increasing the rising HF low Impedance? The OpAmp drives an emmiter follower in this case. Obviously the OLG is greatest at LF. With at HF I would like perfect low Zout but LF alittle higher Zout!.
Regards
Kevin
