(1) The deviation of each output from the average of OUT0-15 constant current. It is calculated by Equation 1 in Table 1.
(2) The deviation of average of OUT1-15 constant current from the ideal constant-current value. It is calculated by Equation 2 in Table 1.
The ideal current is calculated by Equation 3 in Table 1.
(3) The line regulation is calculated by Equation 4 in Table 1.
(4) The load regulation is calculated by Equation 5 in Table 1.
