So here's my problem. I have a pair of noise-cancelling in-ear headphones, and they require a AAA battery. Batteries are expensive so I only use rechargeable ones, but those have a lower capacity (700 maH) and don't last long. I want to make it last longer by putting several of them together into a battery pack. However, that would need to be regulated down to the voltage of a single AAA battery, 1.5v, but I only have 5v regulators.
What I'm thinking of doing is putting a resistive voltage divider on the output of the 5v regulator that would take the voltage down to the 1.5v that the headphones are rated for. Would that work?
