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 m
odule is stable as well as getting the best transient
response. See the Tunable Loop section for details.
