I ordered a couple of parts from MicrochipDirect. The overall experience was very positive: rather quick delivery, very reasonable shipping costs (considering it was sent by courier).

Oh, I forgot to name the part ;-) MCP1804

Have a look at the invoice and find the bug.

Fixed fooprint + LED + shrunk

The MCP1804 is quite a good regulator, very low standby consumption, smaller footprint too. So I switched to that and shrunk the board by 2mm. Can't make it much smaller without moving to insanely small parts.

Code and design files.

Let's see how long I have to wait this time. On the positive side, OSHPARK shouldn't be affected by this year's Chinese New Year (10. and 11. Febr. 2013) and the accompanying celebrations.

MCP1804 DIP friendly(er)

I had to file down the friggin' headers again... You have to love those 29.5mil holes. I'll have to get machined headers with round pins. And if these don't fit... I'll turn into a gamma flash.

Unexpected moment of luck

Initially I had put these bridge-pads on there to select which pins are + and - and connect capacitors to them. Today I used this board with an MCP1804-SOP23-5 voltage regulator. I had everything plugged in and was in need of another GND pin. Not just the one going to the chip, bot one going to the load. Thanks to these jumpers I could use the unused pin #5 (top row in the middle) and just bridge it to GND. I need more of these little moments!

Works as guesstimated
