一,产品概述(General Description) MJw嘉泰姆
MJw嘉泰姆
The CXLD6473 is designed for portable RF and wireless MJw嘉泰姆

applications with demanding perfor-mance and space requirements. MJw嘉泰姆

The CXLD6473 performance is optimized for battery- powered systems MJw嘉泰姆

to deliver ultra low noise and low quiescent current. Regulator groundMJw嘉泰姆

current increases only slightly in dropout, further prolonging the batteryMJw嘉泰姆

life. The CXLD6473 also works with low-ESR ceramic capacitors,reducingMJw嘉泰姆

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

hand-held wireless devices. The CXLD6473 consumes less than 0.01μA in MJw嘉泰姆

shutdown mode and has fast turn-on time less than 50μs. The other MJw嘉泰姆

features include ultra low dropout voltage, high output accuracy,currentMJw嘉泰姆

limiting protection, and high ripple rejection ratio. Available in the 5-leadMJw嘉泰姆

SC-70 and SOT-23 packages.MJw嘉泰姆
