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 LT3008 is tested and specifi ed under pulse load conditions
such that T
at – 40°C and 125°C is assured by design, characterization and correlation
with statistical process controls. The LT3008I is guaranteed over the full
– 40°C to 125°C operating junction temperature range.
Note 3: The LT3008 adjustable version is tested and specifi ed for these
conditions with the ADJ pin connected to the OUT pin.

Note 4: 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 the maximum input voltage, the output current range must be
limited. When operating at the maximum output current, the input voltage
must be limited.
Note 5: Dropout voltage is the minimum input to output voltage differential
needed to maintain regulation at a specifi ed output current. In dropout, the
output voltage equals (V
