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 LTC3109 is tested under pulsed load conditions such that
TJ ≈ TA. The LTC3109E is guaranteed to meet specifications from
The l denotes the specifications which apply over the full operating
junction temperature range, otherwise specifications are for TA = 25°C (Note 2). VAUX = 5V unless otherwise noted.

0°C to 85°C junction temperature. Specifications over the –40°C to
125°C operating junction temperature range are assured by design,
characterization and correlation with statistical process controls. The
LTC3109I is guaranteed over the full –40°C to 125°C operating junction
temperature range. Note that the maximum ambient temperature
is determined by specific operating conditions in conjunction with
