Functional operation above the stresses listed in the Recommended Operating Ranges is not implied. Extended exposure to stresses beyond
the Recommended Operating Ranges limits may affect device reliability.

Product parametric performance is indicated in the Electrical Characteristics for the listed test conditions, unless otherwise noted. Product
performance may not be indicated by the Electrical Characteristics if operated under different conditions.
1. R_OL = (2V_IN − V_OUT)/I_OUT
2. In the event of a controlled shutdown, the output will be isolated from the input, but will remain connected to the internal resistor feedback
network. This will cause a small level of reverse current to flow back into the device to ground.
