Note 1: Absolute Maximum Ratings are those values beyond which the life of
a device may be impaired.
Note 2: 0.6 F is the minimum required C
current capability. Depending on the choice of capacitor material, a
somewhat higher value of capacitor may be required to attain 0.6 F over
temperature.

Note 3: The LTC1754ES6-X is guaranteed to meet performance
specifications from 0 C to 70 C. Specifications over the –40 C to 85 C
operating temperature range are assured by design, characterization and
correlation with statistical process controls.
Note 4: Based on long term current density limitations.
