(1) All limits are specified by testing or statistical analysis.
(2) Typical Values represent the most likely parametric norm.
(3) IFULL LOAD is defined in the current limit curves. The IFULL LOAD Curve defines current limit as a function of input-to-output voltage. Note
that 15W power dissipation for the LM1086 is only achievable over a limited range of input-to-output voltage.
(4) Load and line regulation are measured at constant junction temperature, and are specified up to the maximum power dissipation of
15W. Power dissipation is determined by the input/output differential and the output current. Ensured maximum power dissipation will
not be available over the full input/output range.
