一,产品概述(General Description) eea嘉泰姆
eea嘉泰姆
CXLD6475 dual, low-noise, low-dropout regulator delivers eea嘉泰姆

at least 300mA of continuous output current. The output voltageeea嘉泰姆

for each regulator is set independently by trimming. Output eea嘉泰姆

voltages are selectable in 100mV steps within a range of 1.2Veea嘉泰姆

to 3.5V.Typical output noise is 47uVrms, and PSRR is 73dB at eea嘉泰姆

100Hz. The CXLD6475 includes two independent logic-eea嘉泰姆

controlled shutdown inputs and allows the output of each eea嘉泰姆

regulator to be turned of independently.eea嘉泰姆

CXLD6475 includes high accuracy voltage reference, erroreea嘉泰姆

amplifier, current limit circuit and output driver module CXLD6475eea嘉泰姆

has excellent load and line transient response and good eea嘉泰姆

temperature characteristics, which can assure the stability of chipeea嘉泰姆

and power system. And it uses trimming technique to guarantee eea嘉泰姆

output voltage accuracy within±2%.eea嘉泰姆

CXLD6475 is available in SOT-23-6 package which is lead(Pb)-freeeea嘉泰姆
