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.
