*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 other condition above those indicated
in the operation sections of this specification is not implied.

Note 7.1

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.

Note 7.2

When internal power FET operation of these pins is enabled, these pins may be
simultaneously shorted to ground or any voltage up to 3.63V indefinitely, without damage
to the device as long as V

DD33

and V

DDA33

are less than 3.63V and T

is less than 70°C.
