LT3467/LT3467A
ELECTRICAL CHARACTERISTICS The l denotes the speci?cations which apply over the full operating
temperature range, otherwise speci?cations are at T A = 25°C. V IN = 3V, V SHDN = V IN unless otherwise noted. Speci?cations are for both
the LT3467 and LT3467A unless otherwise noted.

Note 2: The LT3467E/LT3467AE are guaranteed to meet performance
speci?cations from 0°C to 85°C, junction temperature. Speci?cations 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.
