The RH3080 is a 0.9A low dropout linear regulator with a
unique architecture featuring a precision current source
and voltage follower which allows the output to be programmed to any voltage between zero and 36V. Multiple
regulators can be paralleled to increase total output current
and spread heat over a system PC board with no need for
heat sinking. The pass transistor collector can be brought
out independently of the circuit supply voltage to allow
dropout voltage to approach the saturation limit of the pass
transistor. A 2.2µF capacitor on the output with an ESR of
less than 0.5Ω is adequate to ensure stability. Applications
with large output load transients require a larger output
capacitor value to minimize output voltage change. Input
circuitry ensures output safe operating area current limiting and thermal shutdown protection. The rated output
current of an RH3080-based part is fixed by internal wire
length/resistance. Linear Technology dice element evaluations are based on parts rated for 0.9A output current.

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.

Performance Characteristics, Pin Functions, Applications Information and
Typical Applications.
