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: Unless otherwise speci?ed, all voltages are with respect to V OUT .
The LT3082E is tested and speci?ed under pulse load conditions such
that T J ? T A . The LT3082E is 100% tested at T A = 25°C. Performance at
–40°C and 125°C is assured by design, characterization, and correlation
with statistical process controls. The LT3082I is guaranteed to meet all
data sheet speci?cations over the full –40°C to 125°C operating junction
temperature range. The LT3082MP is 100% tested and guaranteed over
the –55°C to 125°C operating junction temperature range.
Note 3: Minimum load current is equivalent to the quiescent current of
the part. Since all quiescent and drive current is delivered to the output
of the part, the minimum load current is the minimum current required to
maintain regulation.
Note 4: For the LT3082, dropout is speci?ed as the minimum input-to-
output voltage differential required supplying a given output current.
Note 5: Adding a small capacitor across the reference current resistor
lowers output noise. Adding this capacitor bypasses the resistor shot
noise and reference current noise; output noise is then equal to error
ampli?er noise (see the Applications Information section).
Note 6: Diodes with series 1k resistors clamp the SET pin to the OUT pin.
These diodes and resistors only carry current under transient overloads.
Note 7: Load regulation is Kelvin-sensed at the package.
Note 8: This IC includes overtemperature protection that protects the
device during momentary overload conditions. Junction temperature
exceeds the maximum operating junction temperature when
overtemperature protection is active. Continuous operation above the
speci?ed maximum operating junction temperature may impair device
reliability.
