I have used some TV baseband distribution amps.
The first one I tried wasn't good though, due to it's DC restoration
function, based on the sync tips.
It resulted in distortion towards the positive end of the 10MHz sin, though
it may be possible to find a compromise signal strength that is OK, or

One other thing to consider with LDOs: some types can go unstable and
oscillate with
the wrong (combination of) capacitors on input and output. So any time you
design in
an LDO, it is important to closely scrutinize the datasheet and application
note(s) and
heed their warnings. Unless you like

Do not overlook that electrolytics are variable capacitors, depending
on pretty much anything and therefore may increase noise in the
up-to-around-a-Hz domain.
