Sorry for the short and nondescript title - there's apparently a bug that limits some people from posting with long titles.
Here's my problem. I have a few devices that use some pretty unique batteries, but they're expensive and hard to come by. There are other batteries that will fit and work, but they're more than too powerful for the device. Obviously, the batteries are connected in series to the device itself. I know the relationship between the batteries mathematically. I attached a schematic of what I'm trying to do. For simplicity, I just used and LED as the "device" that I'm trying to power and used some simpler voltages than the exact ones I'm using. The top shows the device being powered by either two or three (or more) batteries. The bottom is what I would like to accomplish.
So, is there an IC or a regulator that I could put in series to this that would produce the correct output regardless of how many batteries I have in series? That way, I could have a standard circuit that I could use between all devices. Is that possible?
Thanks a million!
