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

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.
