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: 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: 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: 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 5: Guaranteed by design, characterization, or correlation to other
tested parameters.
Note 6: For compliance with 883 revision C current density specifications,
the RH1085 is rated to 2A.
