The second one is smaller, delivers more current and requires less components, so if you want either 3.3V or 5V the second is better. I usually use these because they are regulated (and very stable), use small components (just three ceramic capacitors the 1595) and, most important, they deliver a reasonable amount of current (100mA the adjustable version, 125mA the fixed voltage one). And.. no, I'm not from Maxim ;) | |

I was thinking of using a cr123a as a last resort, because it’s small but still delivers 3v. I might be inclined to agree with you about coin cells - they’re more trouble than they’re worth. | |
