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 specifications

from 0°C to 125°C junction temperature. Specifications 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 specifications apply to the VP trim bits in REG0 using

a 50mV LSB and do not include the additional VPLUS trim bit. See

Registers and OTP in the Applications Information section.

Note 5: This IC includes over-temperature protection that is intended

to protect the device during momentary overload conditions. Junction

temperature will exceed the maximum operating junction temperature

when over-temperature protection is active. Continuous operation above

the specified 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.
