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: The LT3022 regulator is tested and specified under pulse load
conditions such that T
Performance of the LT3022E over the full –40°C and 125°C operating
junction temperature range is assured by design, characterization and
correlation with statistical process controls. The LT3022I regulators are
guaranteed over the full –40°C to 125°C operating junction temperature
range. High junction temperatures degrade operating lifetime. Operating
lifetime is derated at junction temperatures greater than 125°C.
Note 3: This IC includes overtemperature protection that is intended
to protect the device during momentary overload conditions. Junction

Continuous operation above the specified maximum operating junction
temperature may impair device reliability.
Note 4: Minimum input voltage is the voltage required by the LT3022 to
regulate the output voltage and supply the rated 1A output current. This
specification is tested at V
minimum input voltage required for regulation equals the regulated output
voltage V
Note 5: Maximum junction temperature limits operating conditions. The
regulated output voltage specification does not apply for all possible
combinations of input voltage and output current. Limit the output current
range if operating at maximum input voltage. Limit the input-to-output
voltage differential range if operating at maximum output current.
