The S9V11F3S5C3 switching step-up/step-down regulator efficiently 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.
