Input voltage: 2 V to 16 V Fixed 3.3 V or 5 V (selectable) output with +5/-3% accuracy (can be changed to 6 V using the SEL pin) Typical maximum continuous output current: 1.5 A Features a precision-adjustable low-voltage cutoff with hysteresis Power-good indicator and power-saving feature The S9V11F3S5CMA 3.3V Step-Up/Step-Down Regulator w/ Adjustable 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 2 V to 16 V (Note: minimum start-up voltage is 3 V, but it operates to 2 V after that). The regulator also has a precision-adjustable 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. Features 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) Typical maximum continuous output current: 1.5 A Precision-adjustable low-voltage cutoff with hysteresis can be used to protect 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
