PACKAGE/ORDER INFORMATION
Consult LTC Marketing for parts specifi ed with wider operating temperature ranges.
Note 2: The LT3591E is guaranteed to meet performance specifi cations
from 0°C to 85°C operating junction temperature range. Specifi cations
over the –40°C to 85°C operating junction temperature range are assured
by design, characterization and correlation with statistical process controls.
