High speed op amp with output current limiting

Hi, I'm looking for a +/- 5V (or greater) op amp with >200MHz BW. Normal operation would be 50mA peak AC into a 30 to 50 ohm load. However, there are times the load will drop to near zero and I don't want to exceed the temp ratings and possibly damage the part. I would like the amp to shut down or otherwise limit the current during these times. Is there a high speed op amp with this limiting built-in, or do you have a suggested circuit to accomplish this?

Thanks very much.
