Absolute Maximum Ratings indicate limits beyond which damage to the device may occur, including inoperability and degradation of

device reliability and/or performance. Functional operation of the device and/or non-degradation at the Absolute Maximum Ratings or

other conditions beyond those indicated in the Recommended Operating Conditions is not implied. Operating Range conditions indicate

the conditions at which the device is functional and the device should not be operated beyond such conditions. For guaranteed

specifications and conditions, see the Electrical Characteristics table.

(2)

VDD and VDR are outputs of the internal linear regulator. Under normal operating conditions where VIN > 5.5V, they must not be tied to

any external voltage source. In an application where VIN is between 3.3V to 5.5V, it is recommended to tie the VDD, VDR and VIN pins

together, especially when VIN may drop below 4.5V. In order to have better noise rejection under these conditions, a 10

Ω, 1μF input

filter may be used for the VDD pin.
