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...!

I'm planing a version with LT3045 too (500mA).

They will drive my 4 pieces of DAC filter OPAs (+/- 15V)...

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....

You could put an Lt3045 in series with the TPS7A4700 for additional PSRR and lower ripple

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
