I wasn't sure where to post this cuz its not a mechanical/high voltage issue, but it does have to do with power. I need a 5V supply for my circuit but I also need a small battery. So I'm using two stacked coin cell batteries (3V each) and regulating that down to 5V. However upon connecting the power…

Get a millampere meter and put it in the circuit and operate it. Look at peak current demands.
