Best low noise regulator?

[jackinnj]

i will run the experiment in real time with a pair of LDO's like the LT1963A and LT3015 -- more common than the Jung regulator these days and requiring equal care in selection of the output reactive loading.

Am I reading this right? The load regulation graph on page 11:

http://cds.linear.com/docs/Datasheet/1963afe.pdf

Load regulation becomes negative at high temperatures. Then we have negative output resistance. Perhaps this is some sort of feedforward EC regulator design. That's rather interesting.

Thanks for the tests Jackinnj.

This is the bestest circuit of low noise regulator.
This is Russian answer to Salas's The simplistic Salas low voltage shunt regulator .
Our circuit works better, then Salas scheme.

Changing R14 and R33 to 100R would improve transient headroom and glitching behavior without losing anything.

Before counting junctions or after?

It is hardly comparable to Salas, least of all for not being shunt. Or simple.

It is a variant of Jung super-regs but whether it actually performs better than ALW's implementation is hard to say at a casual glance. Not too likely with that 5532...

You have any noise measurements we can compare?

Put Jung for Salas and we start comparing.

Положить Jung для Салас, и мы начинаем сравнивать.

Salas, I understand english very well, mate.

Have any news in this forum ???

I don't know if; ''belleson'' is mentioned, no experience with these

I fried two regs like those : they should do the effort to have better data for both positiv & negativ regs about the programmation résistors !

Not so hard to putt one screen with a full range of output voltage for the two regs in each datasheet to allow a symetric voltage ! But no,to hard to do for them at Linear T..... equation is a mess up for beginners !I ended up with TI instead !

In what way, I'm curious.
