I have it now in front of me. Uses AD797 opamp , three tranys, zener
diodes and LM329 reference, resistors and caps, a kind of bootstrap
design, very fine.  There's also a measurement curve of rejection.
Certainly a very good design, although I feel it is not quite cheap, a
bit complicated, too much components for my applications, and maybe
you'll end up with oscillations because of pcb design...  Not the thing
I was looking for.  W. Jung might forgive me...

What about preregulation ?
