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 VOUT.
The RH3080MK DICE is tested and specified under pulse load conditions
such that TJ ≈ TA.
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: Dropout results from either of minimum control voltage,
VCONTROL, or minimum input voltage, VIN, both specified with respect
to VOUT. These specifications represent the minimum input-to-output
differential voltage required to maintain regulation.
Note 5: The VCONTROL pin current is the drive current required for the
output transistor. This current tracks output current with roughly a 1:60
ratio. The minimum value is equal to the quiescent current of the device.
Note 6: SET pin is clamped to the output with diodes. These devices only
carry current under transient overloads.
Note 7: 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 LT3080 data sheet and Application Note AN83).
Note 8: Dice are probe tested at 25°C to the limits shown in Table 1.
Except for high current tests, dice are tested under low current conditions
which assure full load current specifications when assembled.
Note 9: Dice that are not qualified by Linear Technology with a can
sample are guaranteed to meet specifications of Table 1 only. Dice
qualified by Linear Technology with a can sample meet specifications
in all tables.
Note 10: This IC includes overtemperature protection that is intended
to protect 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.
Note 11: Current limit may decrease to zero at input-to-output differential
voltages (VIN – VOUT) greater than 26V. Operation at voltages for both IN
and VCONTROL is allowed up to a maximum of 36V as long as the difference
between input and output voltage is below the specified differential (VIN
– VOUT) voltage. Line and load regulation specifications are not applicable
when the device is in current limit.
Note 12: Please refer to LT3080 standard product data sheet for Typical
Performance Characteristics, Pin Functions, Applications Information and
Typical Applications.
