The 5V switching (switch-mode) regulator from Dimension Engineering is a high efficiency step-down voltage regulator that is pin-compatible with the common 78XX family of linear voltage regulators.
The DE-SW050 switch mode voltage regulators are designed to be the easiest possible way to add the benefits of switch-mode power to a new or existing project. A DE-SW050 will allow you to take a higher voltage and it step down a 5V output in a compact, efficient manner with an output of 1A. The DE-SW050 family is pin-compatible with the common 78XX family of linear voltage regulators. They have integrated decoupling capacitors, so external capacitors are not generally necessary.
These switch mode regulators are way more efficient than the cheaper 7805 type. This enables your batteries to last much longer. The chart below shows the DE-SW050 compared to the 7805. More info on switch mode regulators by Dimension Engineering.

We also stock a breakout board to make it easy to hook up the regulator.
