In the datasheet we have the figure of OUTPUT CURRENT vs OUTPUT VOLTAGE.
My customer configure OUT0 current to be 60mA, and OUT0 is connected to an LED, according to the plot, as long as the voltage of OUT0 is higher than 0.7V, the current should be almost constant.
I wonder what's the accuracy of the turning point? Is it possible that some device's turning point is 0.7V for 60mA, while other device turning point is 1V for 60mA?
I guess the figure below is just for typical characteristics.
