Why would you need a DE-SW0xx series switch mode voltage regulator?
Easy. Power efficiency.
A regular 78M0x series linear regulator wastes
the power that isn't being put to good use as heat. A
switch mode regulator uses a different approach from just "throwing the
power away", which means batteries run longer and the regulator runs
cooler. These units run up to 87% efficient!
These modules are designed to be pin-for-pin compatible with a standard
78M0x style regulator, so you can plug it into any circuit calling for
a wasteful linear regulator.
These devices are small
too! The body is only 16x22mm, and only 11mm deep, and come pre-pinned
with convenient breadboard compatible 0.1" spacing.
