Note 1: Absolute Maximum Ratings are those values beyond which the life
with statistical process controls.
Note 3: 1.5x mode output impedance is defined as (1.5V – V )/I
of a device may be impaired.

Note 2: The LTC3206E 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
Note 4: Based on long term current density limitations.
Note 5: All values are referenced to V and V levels.
