The 5V switching step-up/step-down voltage regulator S9V11F5 efficiently produces 5 V from input voltages between 2 V and 16 V. (Note: it requires an input voltage of at least 3 V to start, but it can operate down to 2 V after startup.) Its ability to convert both higher and lower input voltages makes it useful for applications where the power supply voltage can vary greatly, as with batteries that start above but discharge below 5 V. The very compact (0.3″ × 0.45″) module has a typical efficiency of over 90% and can supply a typical output current of up to 1.5 A when the input voltage is around 5 V. The flexibility in input voltage offered by this regulator is especially well-suited for battery-powered applications in which the battery voltage begins above 5 V and drops below as the battery discharges. Without the typical restriction on the battery voltage staying above the required voltage throughout its life, new battery packs and form factors can be considered.

Good quality product, supplied in proper ESD packaging.
A super quality product, well-contructed and appropriately supplied in proper ESD packaging.I was also pleasantly surprised at the Pololu website, their range of well-specified products, and hobbyist support.I should however add that I'm not a hobbyist, but a time-served electronics developer.Good quality products like these often save much time on private projects, and money when you factor in the cost of bespoke fabricated PCBs, and shipping costs on just a few parts. So why not simply buy pre-built functional assemblies for less from a name you can trust, and zip up your prototypes in less time?From initial personal experience I can recommend Pololu and products.
