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 specifi ed maximum operating junction
temperature may impair device reliability.
Note 3: The LTC3025 regulator is tested and specifi ed under pulse
loadconditions such that T
tested at 25°C. Performance at –40°C and 125°C is assured by design,
characterization and correlation with statistical process control. The
LTC3025I is guaranteed to meet performance specifi cations over the full
–40°C and 125°C temperature range.

Note 4: For the LTC3025, a regulated output voltage will only be available
when the minimum IN and BIAS Operating Voltages as well as the IN to
OUT and BIAS to OUT Dropout Voltages are all satisfi ed.
Note 5: Operating conditions are limited by maximum junction
temperature. The regulated output voltage specifi cation will not apply
for all possible combinations of input voltage and output current. When
operating at maximum input voltage, the output current range must be
limited. When operating at maximum output current, the input voltage
range must be limited.
Note 6: Dropout voltage is minimum input to output voltage differential
needed to maintain regulation at a specifi ed output current. In dropout, the
output voltage will be equal to V
Note 7: The DFN output FET on-resistance in dropout is guaranteed by
correlation to wafer level measurements.
