Input voltage: 3 V to 16 V Fixed 3.3 V output with +5/-3% accuracy (can be changed to 5 V using the SEL pin) Typical maximum continuous output current: 1.5 A Fixed 3 V low-voltage cutoff with hysteresis protects batteries from over-discharging Power-good indicator and power-saving feature The S9V11F3S5C3 Step-Up/Step-Down Regulator w/ Fixed 3V Low-Voltage Cutoff produces a fixed 3.3 V (default) or 5 V (selectable) output whether it is higher or lower than the input voltage, which can range from 3 V to 16 V. The regulator also has fixed 3.3 V low-voltage cutoff with hysteresis that can be used to prevent battery over-discharge. 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. The S9V11x family uses a buck-boost topology to convert both higher and lower input voltages to a regulated output voltage. It 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. This is particularly useful for battery chemistries that can be damaged when over-discharged, including Li-ion and LiPo. Features Input voltage: 3 V to 16 V Fixed 3.3 V output with +5/-3% accuracy (can be changed to 5 V using the SEL pin) Typical maximum continuous output current: 1.5 A Fixed 3 V low-voltage cutoff with hysteresis protects batteries from over-discharging (quiescent current is approximately 10 µA per volt on VIN when the regulator is disabled) Power-good indicator can be used to tell when the regulator has reached and is maintaining its target output voltage Power-saving feature maintains high efficiency at low currents (quiescent current is less than 1 mA while enabled) Integrated over-temperature and short-circuit protection Show more
