Output Capacitor Selection
Selecting the proper output capacitor is based on the
desired output ripple voltage. Ceramic capacitors with low
ESR values will have the lowest output ripple voltage and
are strongly recommended. The output capacitor requires
either an X7R or X5R dielectric.

Feed ? Forward Capacitor Selection (Adjustable Only)
The feed-forward capacitor sets the feedback loop
response and acts on soft-start time. A minimum 18 pF
feed-forward capacitor is needed to ensure loop stability.
Having feed-forward capacitor of 1 nF or higher can
increase soft ? start time and reduce inrush current. Choose a
small ceramic capacitor X7R or X5R or COG dielectric.
