Notes:
2. Exceeding the absolute maximum ratings may damage the device.
3. The device is not guaranteed to function outside its operating ratings.
4. Devices are ESD sensitive. Handling precautions are recommended. Human body model, 1.5kΩ in series with 100pF. Machine model, 200pF.
5. Reference voltage is not referenced to ground. The reference is between the IN and FB pins.
