Sjöström Super Regulators

fossil2k · 12th October 2007, 12:46 AM

What you guys think about this voltage regulator? The schematic I got is a little crappy but that all I can get from this website below. Do you think its worth a try to build it?

Full schematic is can be found here.

fossil2k, the designer of that is peranders on this forum.

Although I have not used his designs, I know of people who have done so with success.

I'm thinking of building the super regulator to replace those normal LM78 & 79 in my CPD. Now, I have to open up the hood to see if there is enough space to fit in the boards.

Have you seen other circuits in his website? Does the bridge rectifier make significant different for an amplifier?

Direct paralelling of BJTs and OP-amps? I'm not convinced, sorry.

Some info on practical building an ORIGINAL superreg is here:

The original design series is here:

http://waltjung.org/PDFs/Regs_for_High_Perf_Audio_1.pdf

Part 2 is also on Walt's site.

This is an option for two types of parts, SO08 or DIL08 opamps and TO126 or TO220 transistors. I normally try to have more than one alternative especially when it comes to essential parts like semiconductors.... so only one type at the time

More to read about the super regulator
Super Regulator, collecting the facts

It's quite right that I have got inspiration from Didden/Jung.

one PCB for four different packaging options opens up the marketability of the product.

It is really interesting to try this circuit in my cdp. But I need some advise on the board design. It is good to squeeze all the components into a small PCB or do I just design a PCB in a "normal" size?
