Absolute Maximum Ratings*
Operating Conditions**
the absolute maximum ratings not be exceeded or device failure can result. Some power
supplies exhibit voltage spikes on their outputs when AC power is switched on or off. In
addition, voltage transients on the AC power line may appear on the DC output. If this
possibility exists, it is suggested that a clamp circuit be used.
