Note 1: Absolute Maximum Ratings are those values beyond which the life
of a device may be impaired.
Note 2: The LT1615E and LT1615E-1 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. The
LT1615I/LT1615I-1 is guaranteed to meet performance specifications over
the –40°C to 85°C operating temperature range.
Note 3: Bias current flows into the FB pin.
