Hi Folks,

I'm working on a battery powered consumer product that will use a 3V
button cell.  I think we've settled on the CR2032 which has a capacity
of 225uAH.  Our circuit will use an ATtiny13 @ 1MHz along with a few
other items.  The total current consumption is about 2.65ma when
always ON.  I think I can reduce that to about 460uA by cycling the power.

My question to the group - can I just use the battery or do you think
I'll need some type of regulator?  

The application will be mostly in the off state.  I'm planning to have
the unit ON after being plugged into the  item to be controlled and
then after 10 minutes go into the low power mode and then after 30
minutes turn itself off.

Thanks,

Richard Cooke
