Re: Re: 2103 forces dual supply?

2006-04-26 by Steve Franks

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.
