2.5 - 9V Fine-Adjust Step-Up/Down Voltage Regulator S9V11MA

The S9V11MA 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 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.

These regulators have short-circuit protection, and thermal shutdown prevents damage from overheating; they do not have reverse-voltage protection. Note that the startup current is limited to approximately 700 mA until the output voltage reaches the nominal voltage; after startup, the available current is a function of the input voltage
