Note 1:
Absolute Maximum Ratings indicate limits beyond which damage to the device may occur. Operating Ratings indicate conditions for which the device is
intended to be functional, but specific performance is not guaranteed. For guaranteed specifications and the test conditions, see the Electrical Characteristics.
Note 2:
Power dissipation is kept in a safe range by current limiting circuitry. Refer to Overload Recovery in Application Notes. The value
θ
for the LLP package
is specifically dependent on PCB trace area, trace material, and the number of thermal vias. For improved thermal resistance and power dissipation for the LLP
package, refer to Application Note AN-1187.
Note 3:
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

= (T

. All numbers apply for packages soldered directly into a PC board. Refer to Thermal Considerations in the Application Notes.
Note 4:
For testing purposes, ESD was applied using human body model, 1.5k
in series with 100pF.
Note 5:
Typical Values represent the most likely parametric norm.
Note 6:
All limits are guaranteed by testing or statistical analysis.
Note 7:
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.
Note 8:
Load and line regulation are measured at constant junction temperature, and are guaranteed up to the maximum power dissipation of 15W. Power
dissipation is determined by the input/output differential and the output current. Guaranteed maximum power dissipation will not be available over the full input/output
range.
Note 9:
Dropout voltage is specified over the full output current range of the device.
Note 10:
The minimum output current required to maintain regulation.
