ELECTRICAL CHARACTERISTICS

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

of a device may be impaired.

Note 2: Based on long-term current density limitations.

The q denotes the specifications which apply over the full operating

temperature range, otherwise specifications are at TA = 25°C. VIN = 3.3V unless otherwise noted.

Note 3: The LTC3202E 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.
