一,产品概述(General Description) wM9嘉泰姆
wM9嘉泰姆

The CXLD6471 is designed for portable RF and wireless applications wM9嘉泰姆

with demanding perfor-mance and space requirements. The CXLD6471 wM9嘉泰姆

performance is optimized for battery-powered systems to deliver ultra wM9嘉泰姆

low noise and low quiescent current. A noise bypass pin is available forwM9嘉泰姆

further reduction of output noise.Regulator ground current increases wM9嘉泰姆

only slightly in dropout, further prolonging the battery life. ThewM9嘉泰姆

CXLD6471 also works with low-ESR ceramic capacitors, reducing wM9嘉泰姆

the amount of board space necessary for power applications, critical wM9嘉泰姆

in hand-held wireless devices. The CXLD6471 consumes less than 0.01wM9嘉泰姆

μA in shutdown mode and has fast turn-on time less than 50μs. The wM9嘉泰姆

other features include ultra low dropout voltage, high outputwM9嘉泰姆

accuracy, current limiting protection, and high ripple rejection wM9嘉泰姆

ratio. Available in the 5-lead of SC-70, SOT-23 packages.wM9嘉泰姆
