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: Unless otherwise speci ed, all voltages are with respect to V
OUT
.
The LT3092E is tested and speci ed under pulse load conditions such
that T

A
= 25癈. Performance at
40癈 and 125癈 is assured by design, characterization, and correlation
with statistical process controls. The LT3092I is guaranteed to meet all
data sheet speci cations over the full 40癈 to 125癈 operating junction
temperature range. The LT3092MP is 100% tested and guaranteed over
the 55癈 to 125癈 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.

The l denotes the speci cations which apply over the full operating
temperature range, otherwise speci cations are at T

= 25癈. (Note 2)
Note 4: For the LT3092, 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 (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: Current 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.
