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.

material, and the number of layers and thermal vias. For improved thermal resistance and power dissipation for the WSON package,

refer to Application Note AN-1187 Leadless Leadframe Package (LLP) (SNOA401).. Exceeding the maximum allowable power

dissipation will cause excessive die temperature, and the regulator will go into thermal shutdown.

(3)

If used in a dual-supply system where the regulator load is returned to a negative supply, the LP2989 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.
