(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 under "recommended operating
conditions" is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
(2)
The input negative-voltage and output voltage ratings may be exceeded if the input and output current ratings are observed.
(3)
This value is limited to 4.6 V maximum.
(4)
The package thermal impedance is calculated in accordance with JESD 51-7.
