Does your oscillator have a VRef output? If so, use that instead of a regulator. It's cleaner and usually temperature compensated.

With a multiturn pot and a 78L05 I can get a 0 to 5V EFC to tune
an OCXO on desired freq. But... maybe other voltage regulators
or other scheme have better temp stability than the old 78L05.
Before I crawl lost in new'ish fancy regulator land does anybody
know the killer solution/IC for this job ?
