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

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

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

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

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

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

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

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

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

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

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

SC-70 and SOT-23 packages.cvi嘉泰姆
