Notes:
Stresses greater than those listed under MAXIMUM RATINGS
may cause permanent damage to the device. This is a stress rating
only and functional operation of the device at these or any other
conditions above those indicated in the operational sections of this
specification is not implied. Exposure to absolute maximum rating
conditions for extended periods may affect reliability.
1. Input & output negative-voltage ratings may be exceeded if the
input and output curent rating are observed.
2. Output positive-voltage rating may be exceeded up to 4.6V
maximum if the output current rating is observed.
3. The package thermal impedance is calculated in accordance with
JESD 51.
