A minimum value of output capacitance is required for proper operation. Adding additional capacitance at the load further improves
transient response.
(10) This is the calculated maximum. The minimum ESR requirement often results in a lower value. See the Application Information section
for further guidance.
(11) This is the typcial ESR for all the electrolytic (nonceramic) output capacitance. Use 4 m
as the minimum when using max-ESR values
to calculate.
