G990

Global Mixed-mode Technology Inc. 1.6X Linear Fan Driver G990 Features „ VO Follows 1.6 Times of VSET „ 150mV Dropout @ 0.5A „ Over Current and Over Temperature Protection „ Enable Pin „ 10µA Quiescent Current in Shutdown „ Power SOP-8 Package Applications „ Notebook Computer Fan Driver „ Battery Powered Systems „ Motherboards „ Peripheral Cards 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. The G990 is available in the power SOP-8 package. Ordering Information ORDER NUMBER G990P11U Note: P1: SOP-8 1: Bonding Code U: Tape & Reel MARKING G990 TEMP.
