Notes

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

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

3. Devices are ESD sensitive. Handling precautions recommended. Human body model: 1.5kΩ in series with 100pF.

4. Specification for packaged product only.

5. Dropout voltage is defined as the input-to-output differential at which the output voltage drops 2% below its nominal value that is initially

measured at a 1V differential. For outputs below 2.7V, the dropout voltage is the input-to-output voltage differential with a minimum input

voltage of 2.7V.
