NCT3940S

The NCT3940S 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 supports an enable pin to control the output voltage.
