I see. Here's an idea. Adjust Ccomp for taste (i.e. until stable).

sorry - never used those . . .

but every toroid I used had a label on it and sometimes a spec sheet as well.

You really have no diagram ?

try looking on line perhaps

Found an error on the boards - the leds are supposed to be connected to the input rail, not to the midpoint of R1 and Q1 (I've put them as an alternative for R2 and this is incorrect).

Will fix.

Hi Salas and all,
I was off the theme 'shunt reg' for some time, I'm back now and am very pleased with what you did! James, your routing is extraordinary! Supershort paths and elegance whereever you look. I will immediatly copy it for my p2p efforts.

One very worthful advantage of such a 'simple' low-parts count regulator is, you can place it close to the load and you can build several of them for a given circuit.

thanks,
Rüdiger

Yes, very practical. Keep in mind that the very low output impedance blends stages and channels less, so you may use not that many, especially when utilizing local RC decoupling on your circuits.
