Hello I have two links here with LM723 circuits:
http://schematics.circuitdiagram.net/viewer.php?id=klz1250398478f.jpg
This is the regular approach, like in the datsheet, and most of these circuits.
However, here is one weird circuit:
http://virtuatec.com.br/pages/Fonte-0V-%E1-50V-5A.html
where the output of the LM723 is routed via 100 KOhms to the VC+ input.
Can this work, and how??
I don't understand it. It looks backwards to me, at least.
I have been looking at these, and some other circuits, during a project developing a linear power supply (on request), we have now abandoned the LM723 approach.
So a solution is not urgent (anymore).
Would be happy though to see an explanation how and why this circuit can work, or is it wrong?
I would request a valid explanation (I did some hours guesswork myself)- maybe if you use or have used the LM723 yourself. I also have 2 of these chips here, have built this 2nd circuit, but then did not power it up.
