I still don't understand why you're even considering a linear regulator when using batteries though. Surely a switching reg would give you much better efficiency?alias_neo wrote:This would chain tot he regulated PS we're creating above with a voltage of 7.4V (2x 3.7v cells).
Good point, and they aren't to drop below 3V or they become damaged.
I suppose I could go for a switching regulator but even a low drop linear reg is reasonably efficient.
I'm making it for... and giggles more than any practical, purpose, but I suppose if I'm going to share the design I should at least do it right for those who will use it properly >_<
