3 / 18 page LT3467/LT3467A 3 3467afe ELECTRICAL CHARACTERISTICS Note 1: Stresses beyond those listed under Absolute Maximum Ratings may cause permanent damage to the device. Exposure to any Absolute Maximum Rating condition for extended periods may affect device reliability and lifetime. Note 2: The LT3467E/LT3467AE are guaranteed to meet performance specifications from 0°C to 85°C, junction temperature. Specifications over the –40°C to 85°C operating junction temperature range are assured by design, characterization and correlation with statistical process controls. The LT3467I/LT3467AI are guaranteed over the full –40°C to 125°C operating junction temperature range. The l denotes the specifications which apply over the full operating temperature range, otherwise specifications are at TA = 25°C. VIN = 3V, VSHDN = VIN unless otherwise noted. Specifications are for both the LT3467 and LT3467A unless otherwise noted.
