Ah, thanks for all the feedback. I was not specific enough. I was more interested in an all 1.8V soution than just a single supply. Which is to say 3.3V is a killer from 2x AAA or from a single LiPo, then you have to run a dc-dc converter, and that does get expensive on your bom. Not to mention those fat inductors for a boost converter with reasonable efficiency. Pretty much rules out using the 2103 for ZigBee/motes when you can fire up an 8-bit uC with only a 1.8V regulator with an Iq of 10uA. Steve [Non-text portions of this message have been removed]
