G996 Global Mixed-mode Technology Inc. 1.6X Linear Fan Driver Features General Description VO Follows 1.6 Times of VSET 150mV Dropout @ 0.5A Over Current and Over Temperature Protection Enable Pin 10µA Quiescent Current in Shutdown Soft Start to Decrease Inrush Current Power SOP-8 and TDFN3X3-8 Package The G996 is a high performance positive voltage regulator designed for use in applications requiring very low dropout voltage at up to 0.5 Amps. The G996 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 G996 provides excellent regulation over variations in line, load and temperature. Applications Notebook Computer Fan Driver Battery Powered Systems Motherboards Peripheral Cards The G996 is available in the power SOP-8 and TDFN3X3-8 package.
