Bajdi did some tests for switch mode voltage regulators:
There are different types of DC-DC regulators. The most common are linear and switch mode regulators. Everyone that has tinkered with electronics has probably used a 78xx series linear regulator. They are easy to use since they don’t need any special components. With most linear regulators you just put a capacitor on the input and one on the output and they will work.
Hey, that’s a Re:load! Sweet!
