一,产品概述(General Description) 
The CXLD6473 is designed for portable RF and wireless
applications with demanding perfor-mance and space requirements.
The CXLD6473 performance is optimized for battery- powered systems
to deliver ultra low noise and low quiescent current. Regulator ground
current increases only slightly in dropout, further prolonging the battery
life. The CXLD6473 also works with low-ESR ceramic capacitors,reducing
the amount of board space necessary for power applications, critical in
hand-held wireless devices. The CXLD6473 consumes less than 0.01μA in
shutdown mode and has fast turn-on time less than 50μs. The other
features include ultra low dropout voltage, high output accuracy,current
limiting protection, and high ripple rejection ratio. Available in the 5-lead
SC-70 and SOT-23 packages.
