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.

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.

Hi Coffin
I'm using a 22pF silver mica for C3 in 5V configuration.
Is it OK ?
Thanks
should be fine, but MLCC/ceremic is better.
I wish to get one pos. and neg. reg board. how can I pay for the mail?
Sorry, not available at Taiwan, HK and China.
should be fine, but MLCC/ceremic is better.
Thanks Coffin
In +5v single mode, C11 is unpopulated.
Is it correct ?
Regards
