Salas low voltage shunt regulator (V 1.0 ) for DAC and more
 
Salas low voltage shunt regulator (V 1.0)for DAC or other project!
Hello!

There are many member love the design of Salas and they require a low voltage pcb Salas again

I like most is vesiont 1, because I have used successfully in the DAC-END.

You can use the DAC, like I'm doing, or for other projects.

V 1.0 design by Salas

Information:

There are three sources that: 2 + and 1 -.

From 5V-30V, the current 10-200mA

So I open the group by making PCB design of low voltage Salas.

You can see Salas design in:The simplistic Salas low voltage shunt regulator

And I use for DAC in:
DAC End by Andrea Ciuffoli group buys.

DAC End 2 - the AD1865N-K with single ended vacuum output stage

There are so many members want me to do this PCB. I find v1.0 very stable Salas low and very low noise. In this PCB you can use for projects ranging from 3 V to use 50v. with 3 outputs including 2 + and an early start - with a maximum response line 250-300ma! you can see by the pictures!

Hi all this is layout for Salas for DAC anf all project low voltage
Min 3 v- 40V.
In this PCB i use the new CCS of V1.2 of Salas, About Shunt i keep design V1., because i likes V1 , it is simple!
You can se circuit and layout!

@quanghao: do you sell a single rail CCS v1.2 PCB? I would need it for +12V output

Hi! you can use one PCB have 3 supply:
have three separate sources, and can separate them
2 x +
1 x -

check the pin out of Q8 in both the +ve regulators. Drain should be pin2, as the other mosFETs are labeled.

Yes! thanks!
Tha V1.2 CCS and V.1 Shunt , it is excellent! I love it!

quanghao, any chance we'll see a V1.2 Salas shunt pcb/kit? :)

Quanghao,

You mention above that the individual sections of the PCB can be separated. The board design looks pretty tight at the junctions...perhaps you can add a dashed line to indicate the cut line for separating? Do you have a BOM list?

Yes! Now I test layout!
Thanks
