Note 1: Stresses greater than those listed under "Absolute Maximum Ratings" may cause permanent damage to
the device. These are stress ratings only, and functional operation of the device at these or any other conditions
beyond those indicated under"Recommended Operating Conditions" is not implied. Exposure to "Absolute Max-
imum Ratings" for extended periods may affect device reliability.
Note 2: Absolute maximum ratings indicate limits beyond which damage to the component may occur. Electrical
specifications do not apply when operating the device outside of its operating ratings. The maximum allowable
power dissipation is a function of the maximum junction temperature, T
J(max),
the junction-to-ambient thermal
resistance,
θ
JA,
and the ambient temperature, T
A.
The maximum allowable power dissipation at any ambient tem-
perature is calculated using: P

Exceeding the maximum allowable power dissipation will
result in excessive die temperature, and the regulator will go into thermal shutdown.
