Note 1:
Stresses beyond those listed under Absolute Maximum Ratings 0°C to 85°C junction temperature. Specifications over the –40°C to may cause permanent damage to the device. Exposure to any Absolute 125°C operating junction temperature range are assured by design, Maximum Rating condition for extended periods may affect device characterization and correlation with statistical process controls. The reliability and lifetime. LTC3109I is guaranteed over the full –40°C to 125°C operating junction
Note 2:
The LTC3109 is tested under pulsed load conditions such that temperature range. Note that the maximum ambient temperature T is determined by specific operating conditions in conjunction with J ≈ TA. The LTC3109E is guaranteed to meet specifications from 3109fb For more information www.linear.com/LTC3109 3 Document Outline Features Applications Description Typical Application Absolute Maximum Ratings Pin Configuration Order Information Electrical Characteristics Typical Performance Characteristics Pin Functions Block Diagram Operation Applications Information Package Description Typical Application Related Parts
