1. Exceeding the absolute maximum rating may damage the device.
2. The device is not guaranteed to function outside its operating rating.

3. The maximum allowable power dissipation of any T_A (ambient temperature) is P_D(max) = T_J(max) – T_A) / θ_JA. Exceeding 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. Dropout voltage is defined as the input-to-output differential at which the output voltage drops 2% below its nominal V_OUT. For outputs below 2.3V,
the dropout voltage is the input-to-output differential with the minimum input voltage 2.3V.
