When using LM336 2.5Vref and 2sk170GR Q5 do we need to connect the jmper JP1 under side of the PCB?

Hi
The jump is design for AD780 outputing 3V. NC for LM336.

cheers

I ordered a single and dual board from Coffin on 7 May and received the boards 10 days later. They are exceptional well made. I built up the single supply board and it worked great; very stable and no oscillations. It made a big difference on my DAC.

Thank you Coffin!

Now I've to spare some time to go building the regs.
PCB are very very nice 😉

Many thanks Coffin 🙂

Hi Coffin

I'm using a 22pF silver mica for C3 in 5V configuration.
Is it OK ?
Thanks

Asked for reg sample board

Hi
My friend designed two regulator with very small size. He is willing to offer PCB sample to member on diyaudio forum.

Dual regulator : SIZE: 82mm X 59mm
Positive regulator : SIZE: 65mm X 41mm
Supply voltage range : 5V -- 80V

here are the pics of the regulators:
dual

positive

This is the PCB:
dual

positive

Schematic:
dual

positive

The mounting on chassis:

each member from DIYAUDIO can ask for one sample PCB(dual or positive). Because the different voltage has different BOM, please tell me output voltage you need. Only 20pcs of samples for each reg.

Applyer only pays the registered airmail shipping fee 3.00USD.
My email address: coffin@diyzone.net

cheers

should be fine, but MLCC/ceremic is better.

Thanks Coffin
In +5v single mode, C11 is unpopulated.
Is it correct ?
