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-4 is guaranteed functional over the operating temperature
range of –40°C to 85°C.

Note 4: The LT1993C-4 is guaranteed to meet specifi ed performance from 0°C to
70°C. It is designed, characterized and expected to meet specifi ed performance
from –40°C and 85°C but is not tested or QA sampled at these temperatures. The
LT1993I-4 is guaranteed to meet specifi ed performance from –40°C to 85°C.
Note 5: This parameter is pulse tested.
Note 6: This parameter is guaranteed to meet specifi ed performance through design
and characterization. It has not been tested.
