CE CHARACTERISTICS
A
TA = 25°C unless otherwise specied.
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: 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 specied maximum operating junction
temperature may result in device degradation or failure.
Note 3: The LTC3531 is guaranteed to meet performance specications
from 0°C to 70°C. Specications over the –40°C to 85°C operating
temperature range are assured by design, characterization and correlation
with statistical process controls.
ELECTRICAL CHARACTERISTICS The ● denotes the specications which apply over the full operating
temperature range, otherwise specications are at TA = 25°C. VIN = 3.6V VOUT = 3.3V unless otherwise noted.
