# What's the difference between a “Switching Regulator” and a “UBEC”

I want to regulate the voltage from a battery down to 5v to power an Arduino and a Wi-Fi webcam. I’m not too keen on a linear regulator as a lot of power is wasted, so that’s led me to look at switching regulators. I’ve also stumbled on UBECs, which seem to do a similar thing.

The two components I am looking at are these:

What's the main difference between these? Is either one more suitable for my purposes? My load will be under 1A.

From the pages Google shows when looking up UBEC it looks like UBEC is a brand name. In any case it seems to be an ordinary SMPS (switch-mode power supply).
