(1) All limits are specified by testing or statistical analysis.
(2) Typical Values represent the most likely parametric norm.
(3) I
FULL LOAD
is defined in the current limit curves. The I
FULL 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.
(5) Dropout voltage is specified over the full output current range of the device.
