| Apr 2, 2012 at 15:43 | comment | added | supercat | I'm not sure how "linearity" would be defined as a useful feature in this context. The advantages of a linear regulator would generally be cost, lack of injected noise on input and output, and (in some cases) ability to respond quickly to changing load conditions. The fact that a switcher's supply current draw increases with decreasing supply voltage may in some cases cause battery voltage to drop more "suddenly", but the effect won't be overly large when using a buck converter for moderate step-down ratio, and it's a result of drawing less current from a good battery than would a linear. | |

If you need the simplest solution that works reliably, you'll need a linear regulator. The bad side is that they literally waste extra voltage as heat, but the up side is that in most cases you only need the regulator and two capacitors to make it work. | |
