(1) Stresses beyond those listed under Absolute Maximum Ratings may cause permanent damage to the device. These are stress ratings only, which do not imply functional operation of the device at these or any other conditions beyond those indicated under Recommended Operating Conditions. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
(2) If Military/Aerospace specified devices are required, contact the Texas Instruments Sales Office/Distributors for availability and specifications.
(3) Power dissipation is kept in a safe range by current limiting circuitry. Refer to Overload Recovery in Application and Implementation. The value RθJA for the WSON 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 WSON package, refer to AN-1187 Leadless Leadframe Package (LLP)
(4) The maximum power dissipation is a function of TJ(MAX) , RθJA, and TA. The maximum allowable power dissipation at any ambient temperature is PD = (TJ(MAX) – T A) / RθJA. All numbers apply for packages soldered directly into a PC board. Refer to Thermal Considerations.
6.2 ESD Ratings
| VALUE | UNIT | |||
|---|---|---|---|---|
| V(ESD) | Electrostatic discharge | Human-body model (HBM), per ANSI/ESDA/JEDEC JS-001(1) | ±2000 | V |
(1) JEDEC document JEP155 states that 500-V HBM allows safe manufacturing with a standard ESD control process.

(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 15 W power dissipation for the LM1086-MIL 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 15 W. 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.
(6) The minimum output current required to maintain regulation.
