Not sure if you mean OPA333 model does not match typical in datasheet. If so I re-iterate that the macro-model is close to the real silicon behavior. We have done extensive research on Zo since the release of the OPA333 datasheet. One number as typical in a datasheet does not tell you much about Zo. That is why we have gone to putting unloaded typical curves for Zo in all newer reeleases of op amp data sheets. It is the shape and relative magnitude of Zo that is more of interest for stability. Let me know if any further questions.
