The W83391TG is paired with all of Nuvoton’s new series of Super IO and Hardware Monitoring IC for DC Fan voltage regulation. The W83391TG provides system designers a high performance and cost-effective solution.

The W833940SN/ W833941SN is a low quiescent current, low dropout linear regulator which is designed with a P-channel MOSFET to power a DC fan and delivers output current up to 500mA. The output voltage follows the 1.6 times on the voltage of VSET pin to dynamic adjust the DC fan speed.
