Note 4:
The LT1993C-2 is guaranteed to meet specified performance from may cause permanent damage to the device. Exposure to any Absolute 0°C to 70°C. It is designed, characterized and expected to meet specified Maximum Rating condition for extended periods may affect device performance from –40°C and 85°C but is not tested or QA sampled reliability and lifetime. at these temperatures. The LT1993I-2 is guaranteed to meet specified
