G990 - Global Mixed-mode Technology

G990 1.6X Linear Fan Driver

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 dissipati.
