Adjustable Output Voltage C3 Load The output voltage is adjusted by connecting a resistor between 14pin (V.ADJ) and 17, 18pin (+Vout). When 14pin is open, the rated output voltage is as follows: -Vout 14 V.adj Open = 2.5V,3.3V,5V BSI-3.3S = +3.3V±5% BSI-5.0S = +5.0V±5% - A voltage difference of 0.6V or more between the Input/ Output is required for output current 4A type.
