Electrical Charateristics
Specifications with standard type are for T
J
= 25C only; limits in boldface type apply
over the full Operating Junction Temperature (T
J
) range. Minimum and Maximum limits are guaranteed through test, design, or
statistical correlation. Typical values represent the most likely parametric norm at T
J
= 25C, and are provided for reference
purposes only. Unless otherwise stated the following conditions apply: V
IN
= 18V, V
OUT
= 3.3V. (Continued)

Note 1:
Absolute Maximum Ratings are limits beyond which damage to the device may occur. Operating Ratings are conditions under which operation of the device
is intended to be functional. For guaranteed specifications and test conditions, see the Electrical Characteristics.
Note 2:
The human body model is a 100pF capacitor discharged through a 1.5k
resistor into each pin.
Note 3:
θ
