Topic: Uno R3 and the LP2985 (Read 590 times) previous topic - next topic


I'm looking at the Uno R3 schematic and the output capacitor of the LP2985 3.3V regulator. Why is Cout 1uF when the datasheet calls for a minimum of 2.2uF?

This is my first look and I'm hoping that I'm missing something simple :) .


Alright, the Mega2560 schematic also shows a 1uF capacitor at the 3.3V output. I've looked at the PDFs and Eagle schematics - they're the same.

Either someone forgot a zero or I'm in need of a basic refresher course. Little help?
