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.
