Note 1:
Absolute Maximum Ratings are those values beyond which the life of
a device may be impaired.
Note 2:
0.6
μ
F is the minimum required C

capacitance for rated output
current capability. Depending on the choice of capacitor material, a
somewhat higher value of capacitor may be required to attain 0.6
μ
F over
temperature.
