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 TA = 25 °C. Above TA = 25 °C the Power Dissipation must be derated at 5.8mW/ °C (for TA
= 70 °C PD = 464mW ; for TA = 125 °C PD = 145mW)
