Arduino Pro Mini Battery Power

I am trying to get a very low power sleep from my 3.3V pro mini and am hoping to avoid the drain of the voltage regulator. Can the 3.3V pro mini be directly powered by a single LiPo cell. That is, can I connect my LiPo cell directly to the RAW pin. Thanks in advance!

I haven't done it yet, but I checked the specs because I had the same idea, and the ATMega168/V used on the Pro Mini 3.3V is supposed to run happily at 8MHz from 2.7-5.5V.

So it should be fine.
