DESCRIPTION
The RH1085 positive adjustable regulator is designed to
provide 3A with higher efficiency than currently available
devices. All internal circuitry is designed to operate down
to 1V input-to-output differential and the dropout voltage
is fully specified as a function of load current. Dropout is
guaranteed at a maximum of 1.5V at maximum output
current, decreasing at lower load currents. On-chip trim-
mingadjuststheoutputvoltageto1%.Currentlimitisalso
trimmed, minimizing the stress on both the regulator and
power source circuitry under overload conditions.
PRECONDITIONING
The RH1085 is pin compatible with older 3-terminal regu-
lators. A 10μF output capacitor is required on these new
device. However, thisisusuallyincludedinmostregulator
designs.

Note 1: See thermal regulation specifications for changes in output voltage
due to heating effects. Line and load regulation are measured at a constant
junction temperature by low duty cycle pulse testing.
Note 3: Dropout voltage is specified over the full output current range of
the device. Test points and limits are shown on the Dropout Voltage curve
in the LT®1085 data sheet.
Note 2: Line and load regulation are guaranteed up to the maximum power
dissipation of 30W for RH1085. Power dissipation is determined by the
input/output differential voltage and the output current. Guaranteed
maximum power dissipation will not be available over the full input/output
voltage range.
Note 4: Guaranteed by design, characterization, or correlation to other
tested parameters.
Note 5: For compliance with 883 revision C current density specifications,
the RH1085 is rated to 2A.

The PDA is specified as 5% based on failures from group A, subgroup 1,
tests after cooldown in accordance with method 5004 of MIL-STD-883
Class B. The verified failures of group A, subgroup 1, after burn-in divided
by the total number of devices submitted for burn-in in that lot shall be
used to determine the percent defective for the lot.
Linear Technology Corporation reserves the right to test to tighter limits
than those given.
