ELECTRICAL CHARACTERISTICS
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: LT3582 only.
Note 3: The LT3582E is guaranteed to meet performance specifi cations
from 0°C to 125°C junction temperature. Specifi cations over the –40°C
to 125°C operating junction temperature range are assured by design,
characterization and correlations with statistical process controls.
Note 4: These specifi cations apply to the V
P
trim bits in REG0 using a
50mV LSB and do not include the additional V
PLUS
trim bit. See
Registers
and OTP
in the Applications Information section.
Note 5: This IC includes overtemperature protection that is intended
to protect the device during momentary overload conditions. Junction
temperature will exceed the maximum operating junction temperature
when overtemperature protection is active. Continuous operation above
the specifi ed maximum operating junction temperature may impair device
reliability.
Note 6: Output voltage is measured under non-switching test conditions
approximating a moderate load current from the output.
