(6) Short circuit current should be limited in duration to no more than 10 seconds. See the Power Dissipation section of Application
Information for more details.
(7) Negative input current implies current flowing out of the device.
(8) Typical values represent the most likely parametric norm as determined at the time of characterization. Actual typical values may vary
over time and will also depend on the application and configuration. The typical values are not tested and are not ensured on shipped
production material.
