* Size your output capacitor to meet the transient loading requirement. If you have a very dynamic load, a larger capacitor will improve
the response to these load steps (see charts 2&3)
(Unless otherwise specified, the following specifications apply over the operating ambient temperatures for the LX8630-xxC with 0 C
T
techniques are used which maintains junction and case temperatures equal to the ambient temperature.)
