Note: use a minimum 2 x 220uF output capacitor. Recommended capacitor is Nichicon CD series, 220uF/35V. If the ambient temperature is less

than -20

O

C, use more than 3 of recommended minimum capacitors.

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.
