3533f
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.
Note2: The LTC3533EDE is guaranteed to meet performance specifi cations
from 0ºC to 85ºC. Specifi cations over the –40ºC to 85ºC operating
temperature range are assured by design, characterization and correlation
with statistical process controls.

ELECTRICAL CHARACTERISTICS
The denotes the specifi cations which apply over the full operating
temperature range, otherwise specifi cations are at T

= 3.3V, unless otherwise noted.
Note 3: This IC includes over-temperature protection that is intended
to protect the device during momentary overload conditions. Junction
temperature will exceed 125°C when over-temperature protection is active.
Continuous operation above the specifi ed maximum operating junction
temperature may result in device degradation or failure.
Note 4: Current Measurements are performed when the outputs are not
switching.
