Hello Preetham,
I searched our archives for OPA552 Zo and didn't find it for that op amp. I did find the Zo curve for the OPA551 which is the unity gain stable version of the same amplifier. The OPA552 Zo will be the same at lower frequencies, but I expect it will deviate somewhat at higher frequencies because it is a decompensated version having higher bandwidth than the OPA551.
The OPA552 is a legacy op amp and it has an older simulation model design. I checked the model and it models Zo as a constant 25 Ohms across frequency.
This is the extent of Zo information we are able to provide for the OPA552.
