The NCT3940S-A is a linear fan driver designed for noise sensitive and power sensitive systems. The device provides low quiescent current and low dropout linear regulation with a P-channel MOSFET capable of providing up to 500mA output current at a fixed voltage gain of 1.6.  The NCT3940S-A supports a Full On function which turns on the internal power MOSFET when FON# is low.
