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 LT3083 is tested and specified under pulse load conditions such that
T J ? T A . The LT3083E is 100% tested at T A = 25°C. Performance of the
LT3083E over the full –40°C to 125°C operating junction temperature
range is assured by design, characterization, and correlation with
statistical process controls. The LT3083I regulators are guaranteed
over the full –40°C to 125°C operating junction temperature range. The
LT3083MP 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 LT3083, dropout is caused by either minimum control
voltage (V CONTROL ) or minimum input voltage (V IN ). Both parameters are
specified with respect to the output voltage. The specifications represent
the minimum input-to-output differential voltage required to maintain
regulation.
Note 5: The V CONTROL pin current is the drive current required for the
output transistor. This current will track output current with roughly a 1:60
ratio. The minimum value is equal to the quiescent current of the device.
Note 6: Output noise is lowered by adding a small capacitor across the
voltage setting resistor. Adding this capacitor bypasses the voltage setting
resistor shot noise and reference current noise; output noise is then equal
to error amplifier noise (see the Applications Information section).
Note 7: The SET pin is clamped to the output with diodes through 1k
resistors. These resistors and diodes will only carry current under
transient overloads.
Note 8: Load regulation is Kelvin sensed at the package.
Note 9: Current limit includes foldback protection circuitry. Current limit
decreases at higher input-to-output differential voltages.
Note 10: This IC includes overtemperature protection that is intended
to protect the device during momentary overload conditions. Junction
temperature will exceed the maximum operating junction temperature
when overtemperature protection is active. Overtemperature protection
(thermal limit) is typically active at junction temperatures of 165°C.
Continuous operation above the specified maximum operating junction
temperature may impair device reliability.
