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

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

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

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

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

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

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

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

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

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

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

SC-70 and SOT-23 packages.Pbu嘉泰姆
