Note 1: All supplies are fully tested at 25 V and an internal 20 V clamp exists for each supply.
Absolute Maximum Ratings
Absolute maximum ratings indicate sustained limits beyond which damage to the device may occur. All voltage param-
eters are absolute voltages referenced to GND. The thermal resistance and power dissipation ratings are measured
under board mounted and still air conditions.
