Notes:
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.
4. Stresses greater than those listed under MAXIMUM RAT-
INGS 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. Ex-
posure to absolute maximum rating conditions for extended
periods may affect reliability.
