LTC3101
ELECTRICAL CHARACTERISTICS The l denotes the specifications which apply over the full operating
temperature range, otherwise specifications are at TA = 25°C. VUSB1 = VUSB2 = VBAT1 = VBAT2 = 3V and VOUT3 = 3.3V, unless
otherwise noted.

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 LTC3101 is guaranteed to meet performance specifications
from 0°C to 85°C. Specifications over the –40°C to 85°C operating
Note 4: The LTC3101 is tested in a proprietary non-switching test mode
that internally connects the error amplifiers in a closed-loop configuration.
Note 5: This IC includes overtemperature protection that is intended
to protect the device during momentary overload conditions. Junction
temperature will exceed 125°C when overtemperature protection is active.
Continuous operation above the specified maximum operating junction
temperature may impair device reliability.
temperature range are ensured by design, characterization and correlation
with statistical process controls.
Note 3: Current measurements are performed when the LTC3101 is
not switching. The current limit values measured in operation will be
somewhat higher due to the propagation delay of the comparators.
