Notes:
1. Exceeding maximum ratings may damage the device.
2. The device is not guaranteed to work outside its operating rating.
3. The maximum allowable power dissipation of any T
4. Devices are ESD sensitive. Handling precautions recommended. Human Body Model.
5. Specification for packaged product only.
6. Regulation is measured at constant junction temperature using low duty cycle pulse testing.
7. Dropout voltage is defined as the input-to-output differential at which the output voltage drops 2% below its nominal V
8. For ADJ option, V
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 cur-

power dissipation will result in excessive die temperature, and the regulator may go into thermal shutdown.
dropout voltage spec does not apply, as part is limited by minimum V
