Note 1:
Absolute Maximum Ratings are limits beyond which damage to the device may occur. For guaranteed performance limits and associated test conditions, see
the Electrical Characteristics tables.
Note 2:
To ensure constant junction temperature, low duty cycle pulse testing is used; thermal effects must be taken in consideration separately.
Note 3:
The Power Dissipation for the SO-8 package is 725mW at T
A
= 25 °C. Above T
A
= 25 °C the Power Dissipation must be derated at 5.8mW/ °C (for T
A
=
70 °C P
D
= 464mW ; for T

= 125 °C P

= 145mW)
