Thanks a lot! I had a look at the files... The lowest i get is
eurocircuits with apporx 9EUR/pce @ 10 pieces and 5.5EUR/pce @ 20.
There is no way i can match your price at these low batch sizes.
Much less with the parts too...
BTW: How hot does IC2, the TS1117 run? It seems to have an awfully small
cooling copper area.
BTW2: Your board is marked as 15V input voltage. But the LM137 needs
>2V voltage difference at these currents. Ie it needs at least 17V if
not 18V input voltage.
Why does it take years to find the answers to
the questions one should have asked long ago?
