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 15W for RH1086MK and 3W for the RH1086MH. 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^®1086 data sheet.
Note 5: Guaranteed by design, characterization, or correlation to other
tested parameters.
Note 6: I_{FULL LOAD} is defined in the Current Limit curves in the standard
data sheet. For compliance with 883 revision C current density
specifications, the RH1086MK is derated to 1A.
