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.
Our Code: MCU-60038
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.
