All limits are specified by testing or statistical analysis.
Typical Values represent the most likely parametric norm.
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.
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.
Dropout voltage is specified over the full output current range of the device.
