1 Note: use a minimum 2 x 220uF output capacitor. Recommended capacitor is Nichicon CD series, 220uF/35V. If the ambient
temperature is less than 0°C, use 3x of the minimum CO.
2 External capacitors may require using the new Tunable Loop⢠feature to ensure that the module is stable as well as getting the
best transient response. See the Tunable Loop⢠section for details.
