[time-nuts] Linear voltage regulator hints...

Thanks for the responses. I had a feeling the answer wouldn't be good,
but was hoping someone would have a suggestion. There are currently a
bunch of regulators in the 'system'. If there were some really good
regulator out there, the shotgun approach would apply...
Of course it is difficult to provide a good reference and pass
transistor on the same die, but it was worth asking.
The thought of temp control of the regulators crossed my mind. Not
planning on going there unless I need to. But it was a thought, maybe if
all else fails...

Technology has a number of them. Your filter caps take out the broadband
stuff, close in is all that really matters.
Got any hints on which ones? Maybe a nice quiet regulator can be
'disciplined' with a better reference.
