Low noise voltage regulator

[DJ]

Any sugestion of very low noise voltage regulator for VCO applications?

You can make your own with a low noise op amp and a JFET series pass element. Put large amounts of capacitance across the reference.

Used with great satisfaction the old 723 ( no noise at the output ).
Don't use in any way the 78 series, about 2 mV p-p wide band noise with any output capacitor ( at least from 1 nF to 1000 uF ).
Now I know the 723 is difficult to find, but for my VCO i use always it.

I'M INTERESTING TOO!!!!!!!!!!!!!

I see the ckts from old (7 years) presicion instrument and found that use the old 723.

Nothing more actual?

Best regards

"a low noise op amp and a JFET series pass element"? I don't know your means exactly. Could you explain in details?

the zener of AD corp. is very low.youcan use cap. to filter .it decide you.
