Note 1:
Absolute Maximum Ratings are those values beyond which the life of a device may be impaired.
Note 2:
The LT1617 and LT1617-1 are guaranteed to meet 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.
Note 3:
Bias current flows out of the NFB pin. 2
