Super Regulator, collecting the facts - Page 12

Here's a link to a Walt Jung EDN article where he shows the bootstrapped approach.

Another excellent resource for the Jung regulator is ALW's site here:

Thanks, that EDn article was new to me. However, I am still
wondering about the origin of the following schematic

Christer, you didn't read the third post from top?

I had the EDN link and read it and the reason why I started this huge thread was that I wondered of a couple of things which the article didn't reveal.

I wonder also where the picture comes from. I've an another picture which is more or less identical but it seems to it comes from a datasheet or application note.

Hm, probably read and forgot. The thread has become somewhat
lengthy.

I might be wrong, but I strongly suspect the picture I posted
above is from some magazine article. Note also that it clearly
notes certain modifications wrt. to some earlier version, which
seems to indicate it is a follow up article to earlier publication.

This must be from a follow-up to the Audio-Amateur article series. The schematic is for a 5V version done by Walt Jung. I recognise the terminology for the terminal names as the ones I initially used in the AA article, part 3.

Eh, why then does it say +14V on the output.

Anyway, I would be interested in this or any other article
discussing the changes of opamp and opamp supply.

This is Andy's updated version and not the Jung regulator.

How is Peranders going to get his all in one regulator PCB done if you guys keep confusing him with all these versions? Just don't show him the version with all FETs instead of BJTs. That is the newest one.

What loads are these regulators intended for ?.

Not much, I suppose. <100 mA?

Fred Dieckmann · 20th October 2003, 04:42 PM

"Not much, I suppose. <100 mA?"

>100 mA DC. The regulators will work better with load currents above 100 mA
than low current loads like 10 or 20 mA.

There is an extremely simple explanation for this for anybody who knows a little electronics.....

Anybody?
