Note 1: Absolute Maximum Ratings are those values beyond which the life

of a device may be impaired.

Note 2: The LTC3466E is guaranteed to meet specified performance from

°C to 70°C. Specifications over the –40°C to 85°C operating range are

assured by design, characterization and correlation with statistical process

controls.

Note 3: Current flows out of the pin.
