Note 1: Absolute Maximum Ratings valid using 20MHz bandwidth limit.
Note 2: LDO5 has a weak leakage to V CC when LDO5 is more than 0.5V above V CC . OUT5 has a weak leakage to V CC when
OUT5 is more than 0.5V above V CC .
Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional
operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to absolute
maximum rating conditions for extended periods may affect device reliability.
