Notes:
1. Absolute maximum ratings indicate limits beyond which damage to the component may occur.
2. The device is not guaranteed to function outside its operating rating.
3. 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 will result in excessive die temperature, and the regulator will go into
thermal shutdown.
4. Devices are ESD sensitive. Handling precautions recommended. Human body model, 1.5k ? in series with 100pF.
5. Specification for packaged product only.
6. I SD = I VIN .
7. Guaranteed by design.
