Note 1: Absolute Maximum Ratings are those beyond which the life of a
device may be impaired.
Note 2: The LTC3204-3.3/LTC3204-5/LTC3204B-3.3/LTC3204B-5 are
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 3: ROL ≡ (2VIN – VOUT)/IOUT
