Hi! > simple, easy to use, DIP chip, take a look at the ADP1111--I've used it Brendan, you hit the target, this was what I was looking for, I'm not an expert on regulators neither: -. Very Few External Components Required -. Low Battery Detector -. 8-Pin DIP or SO-8 Package among others :-) Many thanks!
