(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) If used in a dual-supply system where the regulator load is returned to a negative supply, the LM2986 output must be diode-clamped to
ground.
(4) The output PNP structure contains a diode between the IN and OUT pins that is normally reverse-biased. Forcing the output above the
input will turn on this diode and may induce a latch-up mode which can damage the part (see Reverse Input-Output Voltage).
(5) The maximum allowable power dissipation is a function of the maximum junction temperature, T_J(MAX), the junction-to-ambient thermal
resistance, R_θJA, and the ambient temperature, T_A. The maximum allowable power dissipation at any ambient temperature is calculated
using: P(_MAX) = T_J(MAX) – T_A / R_θJA
For improved thermal resistance and power dissipation for the WSON package, refer to Texas Instruments Application Note Leadless
Leadframe Package (LLP) (SNOA401). Exceeding the maximum allowable power dissipation will cause excessive die temperature, and
the regulator will go into thermal shutdown.
