Hi
I am working on a project with an MMC card and my circuit requires 43mA of current at 3.3V.
I have been using a Vregulator: LP2951 3.3V and things are working.
The next step is to get batteries to power the circuit.
We would like to use coin cell batteries say CR2032 3V, or the 12V mini batteries.
However I do not know whether these batteries can provide this amount of current?
Someone told me about a dc-dc converter. But I do not know what these are, and indeed whether I can boost current with these?
Do dc-dc converters replace the Vregulatr?
If someone could guide me, I would greately appreciate it.
Thank you
