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 current from 20 % to 100 % Max. Load. The output
voltage difference must be within 8 % of the output at full load and nominal input,… … …..… Load Regulation
= ( Vmax. – Vmin.) / Vnom * 100 %
