Electrical Characteristics
VIN = 5V unless otherwise indicated under the
Conditions
column. Limits in
standard type are for T
J
= 25C only; limits in
boldface type
apply over the junction temperature (T
J
) range of -40C to
+125C. 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. (Continued)

Note 1:
Absolute maximum ratings indicate limits beyond which damage to the device may occur. Operating Range indicates conditions for which the device is
intended to be functional, but does not guarantee specfic performance limits. For guaranteed specifications and test conditions, see the Electrical Characteristics.
Note 2:
Thermal shutdown will occur if the junction temperature exceeds the maximum junction temperature of the device.
Note 3:
Applies for packages soldered directly onto a 3” x 3” PC board with 2oz. copper on 4 layers in still air.
