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.

Note_1:
All voltages are referenced to ground. Currents entering the device are specified positive, and currents exiting the device
are negative.
Note_2:
This supply range guarantees that the LOAD voltage is not clamped by the overvoltage limit.
Note_3:
Supply current specified with no load on the LOAD pin.
