Hello, I am thinking about a tiny coin battery powered project based on the SX20.

The data sheets mention 2.7V, but the traces of power consumption versus voltage seem to terminate around 2.2V.

How low can you go?

Also, how important is a voltage regulator?

Would it cause a problem if I ran an SX20 directly off a 3V coin battery with no intervening regulator?

 :shocked:
