(Note: minimum start- up voltage is 3 V, but it operates to 2 V after that.) The compact (0.5″ × 0.6″) module can supply a typical output current of up to 1.5 A when the input voltage is close to the output voltage\u003c\/span\u003e\u003c\/p\u003e\n\n \u003cp\u003eThe S9V11x family of efficient switching regulators (also called switched-mode power supplies (SMPS) or DC-to-DC converters) use a buck-boost topology to convert both higher and lower input voltages to a regulated output voltage. They take input voltages from 2 V to 16 V and increase or decrease them as necessary, offering a typical efficiency of over 85% and a typical output current of up to 1.5 A. The flexibility in input voltage offered by this family of regulators is especially well-suited for battery-powered applications in which the battery voltage begins above the regulated voltage 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.\u003c\/p\u003e\n\n \u003cp\u003eThe different members of this family offer different output voltage options, from fixed voltages with selectable alternatives to adjustable voltages that can be set anywhere between 2.5 V and 9 V using a precision 12-turn potentiometer. Some versions also have an adjustable low-voltage cutoff that can be set anywhere in the 2 V to 16 V output voltage range and used to prevent your battery from over-discharging. This is particularly useful for battery chemistry that can be damaged when over-discharged, including Li-ion and LiPo.\u003c\/p\u003e\n\n\u003ch2\u003e Details for item #2869\u003c\/h2\u003e\n\n\u003ch2\u003e Features\u003c\/h2\u003e\n\n\u003cul\u003e\n\n\u003cli\u003e Input voltage: 2 V to 16 V (note: this regulator requires 3 V to start, but it can operate down to 2 V after startup)\u003c\/li\u003e\n\n\u003cli\u003e Output voltage: 2.5 V to 9 V (precision-adjustable using built-in 12-turn potentiometer)\u003c\/li\u003e\n\n \u003cli\u003eTypical maximum continuous output current: 1.5 A (when input voltage is close to the output; the \u003cem\u003eTypical efficiency and output current\u003c\/em\u003e section below shows how the achievable continuous output current depends on the input and output voltages)\u003c\/li\u003e\n\n\u003cli\u003e Power-good indicator can be used to tell when the regulator has reached and is maintaining its target output voltage\u003c\/li\u003e\n\n\u003cli\u003e Power-saving feature maintains high efficiency at low currents (quiescent current is less than 1 mA while enabled and approximately 7 µA per volt on VIN when regulator is disabled)\u003c\/li\u003e\n\n\u003cli\u003e Integrated over-temperature and short-circuit protection\u003c\/li\u003e\n\n\u003cli\u003e Small size: 0.5″ × 0.6″ × 0.25″ (12.7 × 15.3 × 6.4 mm)\u003c\/li\u003e\n\n\n\u003c\/ul\u003e\n\n\u003ch2\u003e Using the Regulator\u003c\/h2\u003e\n\n\u003cp class=\"note_warning\"\u003e During normal operation, this product can get hot enough to burn you.
