Hi Trashbox,
Berti is right. Basically the PSRR of your LDO is proportional to the loop gain which, for your topology is set by the error amplifier gain.
This is specially true at low frequencies, where parasitic components do not play a significant role in the PSRR performance. Certainly at very high frequencies the story will be different.
