Note 1. Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device.

These are stress ratings only, and functional operation of the device at these or any other conditions beyond those

indicated in the operational sections of the specifications is not implied. Exposure to absolute maximum rating

conditions for extended periods may affect device reliability.

Note 2. Devices are ESD sensitive. Handling precaution recommended. The human body model is a 100pF capacitor

discharged through a 1.5KΩ resistor into each pin.

Note 3. The device is not guaranteed to function outside its operating conditions.

Note 4. Low duty cycle pulse testing with Kelvin connections.

Note 5. Dropout voltage is defined as the input to output differential at which the output voltage drops 1% below the value

measured with a 2V differential.
