LT3082
APPLICATIONS INFORMATION
Protection Features
The LT3082 incorporates several protection features ideal
for battery-powered circuits, among other applications. In
addition to normal monolithic regulator protection features
such as current limiting and thermal limiting, the LT3082
protects itself against reverse-input voltages, reverse-
output voltages, and reverse OUT-to-SET pin voltages.
Current limit protection and thermal overload protection
protect the IC against output current overload conditions.
For normal operation, do not exceed a junction temperature
of 125°C. The thermal shutdown circuit’s temperature
threshold is typically 165°C and incorporates about 5°C
of hysteresis.
The LT3082’s IN pin withstands ±40V voltages with respect
to the OUT and SET pins. Reverse current ?ow, if OUT is

greater than IN, is less than 1mA (typically under 100μA),
protecting the LT3082 and sensitive loads.
Clamping diodes and 1k limiting resistors protect the
LT3082’s SET pin relative to the OUT pin voltage. These
protection components typically only carry current under
transient overload conditions. These devices are sized to
handle ±10V differential voltages and ±15mA crosspin
current ?ow without concern. Relative to these application
concerns, note the following two scenarios. The ?rst sce-
nario employs a noise-reducing SET pin bypass capacitor
while OUT is instantaneously shorted to GND. The second
scenario follows improper shutdown techniques in which
the SET pin is reset to GND quickly while OUT is held up
by a large output capacitance with light load. The Typical
Applications section shows simple, robust techniques for
shutting down SET and OUT together.
