一,产品概述(General Description) 8m1嘉泰姆
8m1嘉泰姆

The CXLD6471 is designed for portable RF and wireless applications 8m1嘉泰姆

with demanding perfor-mance and space requirements. The CXLD6471 8m1嘉泰姆

performance is optimized for battery-powered systems to deliver ultra 8m1嘉泰姆

low noise and low quiescent current. A noise bypass pin is available for8m1嘉泰姆

further reduction of output noise.Regulator ground current increases 8m1嘉泰姆

only slightly in dropout, further prolonging the battery life. The8m1嘉泰姆

CXLD6471 also works with low-ESR ceramic capacitors, reducing 8m1嘉泰姆

the amount of board space necessary for power applications, critical 8m1嘉泰姆

in hand-held wireless devices. The CXLD6471 consumes less than 0.018m1嘉泰姆

μA in shutdown mode and has fast turn-on time less than 50μs. The 8m1嘉泰姆

other features include ultra low dropout voltage, high output8m1嘉泰姆

accuracy, current limiting protection, and high ripple rejection 8m1嘉泰姆

ratio. Available in the 5-lead of SC-70, SOT-23 packages.8m1嘉泰姆
