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, T A . The maximum allowable power dissipation will result in excessive
die temperature, and the regulator will go into thermal shutdown.
2. Devices are ESD sensitive, handling precautions required.
3. Speci?cation for packaged product only.
4. Guaranteed by design.
