Note 1:
Stresses beyond those listed under Absolute Maximum Ratings
Note 4:
Dropout voltage is specified over the full output current range of may cause permanent damage to the device. Exposure to any Absolute the device. Test points and limits are shown on the Dropout Voltage curve Maximum Rating condition for extended periods may affect device in the LT®1085 data sheet. reliability and lifetime.
Note 5:
Guaranteed by design, characterization, or correlation to other
Note 2:
See thermal regulation specifications for changes in output voltage tested parameters. due to heating effects. Line and load regulation are measured at a constant
Note 6:
For compliance with 883 revision C current density specifications, junction temperature by low duty cycle pulse testing. the RH1085 is rated to 2A.
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. rh1085fc 3
