Open source ULN regulator based on LT3042

[iTiberius]

This is a compact ultra low noise regulator I have designed in KiCad during Covid.
The goal was to have a small and capable regulator that may be used in a wide range of applications. It must be able to power my RPi projects and not only. It is based on LT3042.
So nothing special apart the fact is small, compact, open source and able to push 3A in any load.
Zip file contain KiCad files and gerbers as well.

Enjoy !!!

A complete power supply solution, based on same regulator + synchronous rectifier, is available here.

What about the noise of the device ? It has more noise than the LT3042 alone ?

Response to your question is in this analog article.
Increasing Output Current of the Ultralow Noise, Ultrahigh PSRR LT3042 200mA Linear Regulator | Analog Devices

There is a small difference, but as graph shows performance is indeed Ultra Low Noise.

Same regulator is used here with synchronous rectifier. This improve noise and thermal performance.
