Note 1:
Absolute Maximum Ratings are those values beyond which the life of by the input/output differential and the output current. Guaranteed a device may be impaired. maximum power dissipation will not be available over the full input/output
Note 2:
See Thermal Regulation specifications for changes in output range. See Short-Circuit Current curve for available output current. voltage due to heating effects. Line and load regulation are measured at a
Note 4:
Dropout voltage is specified over the full output current range of constant junction temperature by low duty cycle pulse testing. Load the device. Test points and limits are shown on the Dropout Voltage curve. regulation is measured at the output lead ≈1/8" from the package.
Note 5:
Minimum load current is defined as the minimum output current
Note 3:
Line and load regulation are guaranteed up to the maximum power required to maintain regulation. At 25V input/output differential the device dissipation of 15W (3W for the LT1086H). Power dissipation is determined is guaranteed to regulate if the output current is greater than 10mA. sn1086 1086ffs 4
