Note 1: Absolute Maximum Ratings are those values beyond which the life
of a device may be impaired.
Note 2: As long as output current and junction temperature are kept below
the Absolute Maximum Ratings, no damage to the part will occur.
Note 3: The LT1993C-2 is guaranteed functional over the operating
temperature range of –40°C to 85°C.
Note 4: The LT1993C-2 is guaranteed to meet specied performance from
0°C to 70°C. It is designed, characterized and expected to meet specied
performance from –40°C and 85°C but is not tested or QA sampled
at these temperatures. The LT1993I-2 is guaranteed to meet specied
performance from –40°C to 85°C.
Note 5: This parameter is pulse tested.
Note 6: This parameter is guaranteed to meet specied performance
through design and characterization. It has not been tested.
