3.3V Step-Up/Step-Down Voltage Regulator w/ Adjustable Low-Voltage Cutoff S9V11F3S5CMA

The S9V11F3S5CMA step-up/step-down regulator generates a fixed 3.3 V (default) or 5 V (selectable) output regardless of the input voltage (2 V to 16 V). The minimum startup voltage is 3 V, but after that it can operate down to 2 V. The regulator features a precisely adjustable low-voltage cutoff with hysteresis, which can be used to prevent over-discharging of the battery. The compact module can deliver 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 needs 3 V to start, but can operate down to 2 V after startup)
• Fixed 3.3 V output with + 5 / -3% accuracy (can be changed to 5 V via the SEL pin)
• Typical maximum continuous output current: 1.5 A (when the input voltage is close to the output)
• A precisely adjustable low-voltage cutoff with hysteresis can be used to protect batteries from over-discharge (quiescent current is approx. 10 ?A per volt on VIN when the regulator is disabled)
• The power-good indicator can be used to detect when the regulator has reached and maintains its target output voltage
• Power-saving feature maintains high efficiency at low current (quiescent current is less than 1 mA while enabled)
• Integrated over-temperature and short-circuit protection
• Size: 12.7 × 15.3 × 6.4 mm
