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

. Exceeding the maxmimum allowable
power dissipation will result in excessive die temperature, and the regulator will go into thermal shutdown.
5. Devices are ESD sensitive. Handling precautions are recommended. Human body model, 1.5kΩ in series with 100pF.
6. Specification for packaged product only.
7. Regulation is measured at constant junction temperature using low duty cycle pulse testing. Changes in output voltage due to heating effects are
covered by the thermal regulation specification.
8. Dropout voltage is defined as the input-to-output differential at which the output voltage drops 2% below its nominal value measured at 1V differential.
9. Ground pin current is the regulator quiescent current. The total current drawn from the supply is the sum of the load current plus the ground pin
