Notes:

1. Exceeding the absolute maximum rating may damage the device.

2. The device is not guaranteed to function outside its operating rating.

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 1.5kΩ in series with 100pF.

5. Specification for packaged product only.

2.6V, the dropout voltage is the input-to-output differential with the minimum input voltage 2.6V.
