产品概述 返回TOP
The CXFA3173 is a high performance positive voltage regulator designed for use in applications requiring very low dropout voltage at up to 0.5 Amps. The CXFA3173 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 CXFA3173 provides excellent regulation over variations in line, load and temperature. The CXFA3173is available in the power SOP-8 and TDFN3X3-8 package
