For a 500 mA rail powering a sensor or MCU core, the ripple is manageable with a 10 µF ceramic output cap; just don't expect the same noise floor as a lower-frequency regulator. ## Input range 2.05V to 6V — single Li-ion or 3.3V rail The input voltage spans 2.05V min to 6V max, which covers a single-cell Li-ion (3.0-4.2V) or a regulated 3.3V or 5V bus. The 2.05V minimum means it can run deep into battery discharge without dropping out — useful for portable gear. The fixed 2.9V output is not adjustable, so confirm that voltage matches your load; it's a common rail for low-voltage logic or RF front-ends.
