Output current regulation parameters
NOTES:
(f) System parameter only. This value is dependent upon external components and circuit configuration.
(g) This refers to the accuracy of output current regulation under normal operation when the feedback loop incorporating
the current monitor is active. The tolerances of external components are not included in this figure.
