Pololu S9V11F3S5 3.3V Step-Up/Step-Down Regulator

The S9V11F3S5 3.3V Step-Up/Step-Down Regulator 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 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. Input voltage: 2 V to 16 V; Fixed 3.3 V output with +5/-3% accuracy (can be changed to 5 V using the...
