1.6X Linear Fan Driver
Features
General Description
„
The G990 is a high performance positive voltage
regulator designed for use in applications requiring
very low dropout voltage at up to 0.5 Amps. The G990
VO output voltage follows the 1.6 times of VSET voltage until it reaches VIN voltage. The VSET voltage
must be larger than 1V to guarantee VO 1.6 times of
VSET. An enable pin further reduces power dissipation while shut down. The G990 provides excellent
regulation over variations in line, load and temperature.
