LDO open loop plot for SPICE modeling

To make LDO stable by compensation. How to obtain open loop gain phase 
plot to compensate LDO, since it is not available in the datasheet.

Since its very much required for LDO load transient, load regulation 
etc. This information is essential I belive.

From datasheet (not given in block diagram). How to understand its 
internally compensated or externally compensated.
