3x powersupply for rpi

[fboe]

I have used three LT1963 regulators, as described here: http://cds.linear.com/docs/en/datasheet/1963fc.pdf
And you can see the rpi scheamtic here: https://www.raspberrypi.org/documentati ... EDUCED.pdf

Is all you need is just the 3.3 and 1.8 supplies? What was the third one for.
What did you use for the base supply

I just want to advise that I have tried supplying 5v via GPIO pins 2 and 6, as per fboe's original suggestion, and the results were immediately apparent. There is more detail and improvements to the quality of the sound.

This has become one of those changes where I want to listen to all my music collection again because it's all sounding better.

This has to be the simplest and most cost-effective quality improvement possible! Thoroughly recommended.

Then you should try to go all the way, because when I did it, it was an much greater improvement than when just feeding the 5V on the GPIO.

Kind regards,

I still wish you would provide a bit more information
You said you used three VR's what is the 3rd one for
also what was your basic DV voltage source

Thanks that is what I needed to know
I appreciate your patience

Well yes one more question
I went back and read the whole thread. You very clearly explain/show where to connect the 3.3 and the 1.8v supplies but what about the 5v supply.
