Note 1: Absolute maximum ratings indicate limits beyond which damage to the component may occur. Electrical specifications do not apply when operating the de-  
vice outside of its rated operating conditions.  
Note 2: The maximum allowable power dissipation is a function of the maximum junction temperature, T , the junction-to-ambient thermal resistance, θ , and the  
J−A  
J
ambient temperature, T . Exceeding the maximum allowable power dissipation will cause excessive die temperature, and the regulator will go into thermal shutdown.  
A
The value of θ  
(for devices in still air with no heatsink) is 60˚C/W for the TO-220 package, 80˚C/W for the TO-263 package, and 174˚C/W for the SOT-223 package.  
J−A  
The effective value of θ  
can be reduced by using a heatsink (see Application Hints for specific information on heatsinking).  
J−A  
Note 3: ESD rating is based on the human body model: 100 pF discharged through 1.5 kΩ.

Note 4: All limits guaranteed for T  
25˚C are 100% tested and are used to calculate Outgoing Quality Levels. All limits at temperature extremes are guaranteed
