Quad Voltage Reference

Barbouri has updated his voltage reference board design:


Quad Voltage Reference

This is my version 2 board update, which incorporates supply voltage regulation, over-current protection, and trimmer for the 5.000 volt reference all on the same board.


The new board uses a LM2937IMPX-10, which is a positive linear voltage regulator IC with a 10V output at 400mA in a SOT-223-4 package.

Barbouri has shared project the project on OSH Park:
