Deviation is calculated by the formula: (2) The deviation of the OUT0–OUT15 constant current average from the ideal constant current value. Deviation is calculated by the following formula: Ideal current is calculated by the formula: (3) Line regulation is calculated by this equation: (4) Load regulation is calculated by the equation: (5) Not tested.
