Notes:
1. Absolute maximum ratings indicate limits beyond which damage to the component may occur. Electrical speci ? cations 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, TA. The maximum allowable power dissipation will result in excessive die
temperature, and the regulator will go into thermal shutdown.
2. The device is not guaranteed to function outside its operating rating.
3. Devices are ESD sensitive. Handling precautions recommended. Human body model.
4. Specification for packaged product only.
5. I SD = I VIN .
6. See “Typical Characteristics” section for other V EN .
7. Guaranteed by design.
