Note :

(1). Line Regulation : Set output load to full load, Then adjust input voltage from 4.5Vdc to 5.5Vdc (10% change), The output voltage

difference must be within 13 % of the output at full load and nominal input.

(2). Load Regulation : Set input voltage at 5.0Vdc, Then changing the load

voltage difference must be within 8 % of the output at full load and nominal input,…………

..「 Load Regulation
