(1) The maximum power dissipation is a function of T_J(MAX), θ_JA, and T_A. The maximum allowable power dissipation at any ambient temperature is P_D = (T_J(MAX)–T_A)/θ_JA. All numbers apply for packages soldered directly into a PC board. Refer to Thermal Considerations.

(2) Typical Values represent the most likely parametric norm.

(3) All limits are specified by testing or statistical analysis.

(4) 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.

(5) 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.

(6) Dropout voltage is specified over the full output current range of the device.

(7) The minimum output current required to maintain regulation.
