Output Voltage Regulation
The following figures apply to single-output or double-out-
put models with parallel-connected outputs.

Output Regulation of Double-Output Models
Output 1 is under normal conditions regulated to V
independent of the output currents.
V
loaded with more than 10% of I
remains within ±5% of V
regulation with varying load distribution.
Two outputs of a double-output model connected in parallel
behave like the output of a single-output model.

Note: If output 2 is not used, we recommend connecting it in
parallel with output 1. This ensures good regulation and
efficiency.
