What's the current output required?

Low DropOut regulators can be designed to virtually have no drop. An input
voltage of 3.2V can reliably regulated to 3V.

It's the other end that's the problem. Dropping 27V in a linear regulator
can consume some signicant power depending on the current requirements.
