*Stresses above 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 above those indicated in the
operation sections of the specifications is not implied.
Exposure to Absolute Maximum Rating conditions for
extended periods may affect device reliability.

Note
1: VR is the regulator output voltage setting.
2: Dropout voltage is defined as the input to output differential at which the output voltage drops 2% below its nominal value measured at a
1V differential.
3: Varies with type of pass transistor used. Numbers shown are for the test circuit of Figure 3-1.
4: The product of IEXT X VEXT must be less than the maximum allowable power dissipation.
