The S9V11MACMA switching step-up/step-down regulator efficiently produces a finely adjustable output between 2.5 V and 9 V whether it is higher or lower than the input voltage, which can range from 3 V to 16 V. The regulator also has a precision-adjustable low-voltage cutoff with hysteresis that can be used to prevent battery over-discharge.
