Shunt regulator +-15V

[dadod]

This is quite simple shunt regulator with very low output impedance.
I designed two types of PCB, single shunt regulator and double shunt regulator (in case you what supply for two channels) Output current could be set up to 100 mA.

An ambitious design no doubt. But I would lik to see straight lines up to 100khz or at least to 50k. Impedance, phase, noise... the works.

Doable?

I spotted a typing error in the double barrel (winding??) schematic.
I think the "AC 12V" should be "AC 15V"
Okay, enough with the grammarnaziness.
Can the output voltage be adjusted easily by changing some components ???

Why strait line, impedance at 100 kHz is still around 30 mohm.

It can easily work from +-10 to +-30 V.
By the way, thank for spotting a typing error.

Interessted in a cople of pcb´s..

Please let us know if there will; be a group (or other) buy.
Many thanks.

I'm interested i some PCB's too.

I will order some boards for single shunt regulator. Minimum order is 5 pieces, I need 2 for me, so there is going to be 3 left. I don't have intention to order double shunt regulator boards as I don't need them, but if there is interest minimum order is 5 pieces.
By the way, the same shunt regulator is used in GanWire mk2 preamplifier.

 

[brianco]

x2 please (UK shipping)

Many thanks.

Do you have an estimated price for the single barrel boards ??

I think 7 EUR plus shipping 6 EUR, but I will have 3 spare only, not ordered yet.

 

[Ryssen]

"Minimum order is 5 pieces, I need 2 for me,"

Is it possible to order more than 5 then?

 

[jasse]

Well, I'm interested in 4 PCB's, shipped to Sweden.

Does anything stop you from ordering more then 5 boards ???

No, of course not, 5 PCB is minimum order, next is 10 and so on in steps of 5.
I would like to know what interest is single and what for double shunt regulator board.

[To clarify my posts above]
x2 single please. Shipped to UK,

Thanks.

 

[jasse]

Oh, should have been more specific.
I want x4 single PCB's.
To Sweden.

That is 6 board plus 2 for me, total 8.

brianco 2 single boards
jasse 4 single boards

Do you have a BOM for this board ???
I'm thinking mostly about wattage of resistors and physical measurements on the heatsinks.
Other restrictions / guidelines ??
