Notes: 1. Some output voltages may not be possible depending on the input voltage.
2. External capacitors may require using the new Tunable Loop^TM feature to ensure that the module is
stable as well as getting the best transient response (See the Tunable Loop^TM section for details).
3. Unless otherwise indicated, specifications apply over all operating input voltage, resistive load, and
temperature conditions.
