DESCRIPTION
The LT
®
3082 is a 200mA low dropout linear regulator that
can be paralleled to increase output current or spread heat
in surface mounted boards. Architected as a precision
current source and voltage follower, this regulator benefits
many applications requiring high current, adjustability to
zero and no heat sink. The LT3082 withstands reverse
input voltages and reverse output-to-input voltages without
reverse-current flow.
A key feature of the LT3082 is the capability to supply a
wide output voltage range. A precision “0” TC 10μA ref-
erence current source drives a single resistor to program
the output voltage to any level between zero and 38.5V.
The LT3082 is stable with only 2.2μF of capacitance on
the output; the IC uses small ceramic capacitors that
do not require additional ESR as is common with other
regulators.
Internal protection circuitry includes reverse-battery and
reverse-current protection, current limiting and ther-
mal limiting. The LT3082 is offered in the thermally en-
hanced 8-lead TSOT-23, 3-lead SOT-223 and 8-lead 3mm
× 3mm DFN packages.

Thermal Regulation
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 specified, all voltages are with respect to V
OUT
.
The LT3082E is tested and specified 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 specifications 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 specified 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
amplifier 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
specified maximum operating junction temperature may impair device
reliability.
