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 the regulated voltage. The compact (0.45″ × 0.65″) module has a typical efficiency of over 90% and can deliver 500 mA to 1 A across most of the input voltage range.\u003c\/p\u003e\n\n\u003cp\u003eOverview\u003c\/p\u003e\n\n\u003cp\u003eThe stepup\/stepdown voltage regulator S7V8F5 is a switching regulator (also called a switchedmode power supply (SMPS) or DCtoDC converter) that uses a buckboost topology. It takes an input voltage from 2.7 V to 11.8 V and increases or decreases the voltage to a fixed 5 V output with a typical efficiency of over 90%. The input voltage can be higher than  lower than  or equal to the set output voltage  and the voltage is regulated to achieve a steady 5 V.\u003c\/p\u003e\n\n\u003cp\u003eThis flexibility in input voltage is especially wellsuited for batterypowered applications in which the battery voltage begins above the desired output voltage and drops below the target 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. For example:\u003c\/p\u003e\n\n    \u003cp\u003eA 4cell battery holder  which might have a 6 V output with fresh alkalines or a 4.0 V output with partially discharged NiMH cells  can be used with this regulator to power a 5 V circuit.\u003cbr\u003e\n    A disposable 9 V battery powering a 5 V circuit can be discharged to under 3 V instead of cutting out at 6 V  as with typical linear or stepdown regulators.\u003c\/p\u003e\n\n\u003cp\u003eIn typical applications  this regulator can deliver up to 1 A continuous when the input voltage is higher than 5 V (stepping down). When the input voltage is lower than 5 V (stepping up)  the available current decreases as the difference between the voltages increases; please see the graphs at the bottom of this page for a more detailed characterization. The regulator has shortcircuit protection  and thermal shutdown prevents damage from overheating; the board does not have reversevoltage protection.\u003c\/p\u003e\n\n\u003cp\u003eFeatures\u003c\/p\u003e\n\n    \u003cp\u003einput voltage: 2.7 V to 11.8 V\u003cbr\u003e\n    fixed 5 V output with +5\/3% accuracy\u003cbr\u003e\n    typical continuous output current: 500 mA to 1 A across most combinations of input and output voltages (Actual continuous output current depends on input and output voltages.
