Thanks
And what do you think about the results .....
Is it a good idea to use it in a DAC for VREF ?

I replaced the tridents (4 years old model) of my buffalo and the lt3042 regs get to stay. I get more bass. At first I thought the sound a bit sharp but it has mellowed/I have gotten used to it. Like some changes do this brought an urge to spend waay to much time listening to music🙂
I'm glad i tried them. Thanks to zarandok sharing his design it is easy to try them out and see if they suit your dac/taste. As hifi-parts go they really are quite inexpensive.
zarandok has shared a shunt regulator also at pcbaway
Is there a preferred BOM for LT3042 regulator and shunt regulator
Hi samoloko, please see the BOM: http://www.diyaudio.com/forums/attachments/power-supplies/670048d1521626903-ultra-low-noise-psrr-ldo-lt3042-bom_lt3042v1-1-zip
The key components are the reference resistor and capacitor, they must be the highest quality possible.
The shunt is another cup of tee, must be calculated individually! If you wish I can help you...

I'm happy if you have fun with them...🙂
The soldering for me was suprisingly easy (nothing destroyed...), you need only:
- a small tip soldering iron
- good flux fluid
- good eyes (and/or a loupe)
- non trembling hands (some beer helps, but not too much!)
- carefully checking after first pin soldered, maybe correcting!

Hi
Thanks a lot to share your project.
I have ordered a few PCB and i have some questions
On the picture :Yet another ultra low noise high PSRR LDO - LT3042
There are two R = 0 Ohm , one for ILIM and what is the oher one ?
Is it a good idea to have Cin=Cout=Cset ,Murata GJ8 X7R / 1206 / 4,7uF / 50V
What are your advices about the resistor choice ?
Thanks
Serge
If you do not need current limiting, the ILIM pin must be grounded (0R).
The other is the power good feedback, if you need fast startup you must populate this PGFB resistors (e.g. 450k/50k), please see datasheet!
Murata GJ8 is a good choice, these are reduced noise ceramic types.
For Cset would be a good foil cap (w/o piezoelectric effect) the best, but they are very big...
For Rset use thin-film type, they have minimal current noise (and costs more of course).
Cheers!

I am not an engineer or a specialist like you.....
Sorry to ask you stupid questions and to make you waste your time !!!
Serge
No, I'm just a hobbist...🙂
You do not waste my time, but I'm assuming that if you will to assembling such a thing it's the minimum that you read carefully the manufacturers datasheet and app notes. It's your interest...!

Yes great Idea, can you also make it with option to mount it on a heat sink?
Best regards
I've decided not to build these LT3045 modules, because I need on input voltage capability of >20V. The only option is the TPS7A4700.
But if somebody wish I can share the design file and order it for yourself....

Hi zarandok
did you try to design a pcb for adm7150 which has a much more user friendly socket to solder compared to LT3042/5
