Note:

Stresses above the specified parameters could cause permanent damage to the device. This is a stress

rating only and functional operation of the device at any condition above those indicated in the operation

sections of this specification is not implied. When powering this device from laboratory or system power

supplies, it is important that the Absolute Maximum Ratings not be exceeded or device failure can result.

Some power supplies exhibit voltage spikes on their outputs when the AC power is switched on or off. In

addition, voltage transients on the AC power line may appear on the DC output. When this possibility exists,

it is suggested that a clamp circuit be used.
