Note 1:
Absolute Maximum Ratings are limits beyond which damage to the device may occur. Operating Ratings define the conditions under which the device
is intended to be functional. For guaranteed specifications and test conditions, see the Electrical Characteristics.
Note 2:

in series with 100pF.
Note 3:
Thermal shutdown will occur if the junction temperature (T
) exceeds 165°C. The maximum allowable power dissipation (P
) at any ambient temperature
(T
) is P
= (T
– T
)/θ
. This number applies to packages soldered directly onto a 3" x 3" PC board with 2oz. copper on 4 layers in still air. For a 2 layer
