Notes:

1. Absolute maximum ratings indicate limits beyond which damage to the component may occur. Electrical specifications 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, TJ(MAX), the

junction-to-ambient thermal resistance, θJA , 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 precautious recommended. Human body model, 1.5kΩ in series with 100pF.

4. Specification for packaged product only.
