(1) The deviation of each output from the average of OUT0–OUT15 constant-current. Deviation is calculated by the formula:
D (%) =
I_OUTn
- 1 ´ 100
(I_OUT0 + I_OUT1 + ... + I_OUT14 + I_OUT15)
16
.
(2) The deviation of the OUT0–OUT15 constant-current average from the ideal constant-current value.
Deviation is calculated by the following formula:
D (%) =
(I_OUT0 + I_OUT1 + ... I_OUT14 + I_OUT15)
- (Ideal Output Current)

(3) Line regulation is calculated by this equation:
D (%/V) =
(I_OUTn at V_CC = 5.5 V) - (I_OUTn at V_CC = 3 V)
(I_OUTn at V_CC = 3 V)

(4) Load regulation is calculated by the equation:
D (%/V) =
(I_OUTn at V_OUTn = 3 V) - (I_OUTn at V_OUTn = 1 V)
(I_OUTn at V_OUTn = 1 V)
