Hello, would like know, how to get started from scratch to build a LPS that requires a variable voltage from 3v 5v 9v 12v volt volt to run AD-DA converter .
Thanks a lot.I recently designed an ultra Low Noise LPU using two stage filtering using BA00DD0WCP-V5E2 followed by TI's ultra low noise LDO TPS7A9201DSKR.
I actually intended to use it with Allo Boss + RPI Streamer. But before I could fully "enchase" the Streamer, by old time friend Abhishek [@AKT] grabbed it for his Allo DigiOne Signature and found it to be working better than even Allo Shanti LPU he bought.
I am attaching the Schematic and PCB Layout. The PCB / need to be re-worked for Bridge rectifier pads, which I can do if you wish to build it. The Schematic also uses optional 6-48v Opto-Isolated Triggering to turn on the power.
I can spare a PCB, if you are ready to work with the existing pads for the Diode fir the bridge .
Sent you a DM. Please checkFirst sorry for replying late here and to the DM/PM of all other respectable members. Actually I am not very regular to this forum, and to the email box where notifications came.
I had sourced all the components from Element14 and the TPS7A9201DSKR LDO was around Rs 250 . So was the other LDO in the first stage.
unfortunately the Chip shortage has hit almost all the Electronics related hobbies, and almost all popular active components are out of stock ( Plus Aliexpress , the other refuge is long banned by the Govt here ).

I will be hinting the components from other sellers and update this thread accordingly. I must be having around 4-5 PCBs which I can giveaway to forum members. If someone needs PCB files, please DM me.
