一,产品概述(General Description) tv5嘉泰姆
tv5嘉泰姆
CXLD6475 dual, low-noise, low-dropout regulator delivers tv5嘉泰姆

at least 300mA of continuous output current. The output voltagetv5嘉泰姆

for each regulator is set independently by trimming. Output tv5嘉泰姆

voltages are selectable in 100mV steps within a range of 1.2Vtv5嘉泰姆

to 3.5V.Typical output noise is 47uVrms, and PSRR is 73dB at tv5嘉泰姆

100Hz. The CXLD6475 includes two independent logic-tv5嘉泰姆

controlled shutdown inputs and allows the output of each tv5嘉泰姆

regulator to be turned of independently.tv5嘉泰姆

CXLD6475 includes high accuracy voltage reference, errortv5嘉泰姆

amplifier, current limit circuit and output driver module CXLD6475tv5嘉泰姆

has excellent load and line transient response and good tv5嘉泰姆

temperature characteristics, which can assure the stability of chiptv5嘉泰姆

and power system. And it uses trimming technique to guarantee tv5嘉泰姆

output voltage accuracy within±2%.tv5嘉泰姆

CXLD6475 is available in SOT-23-6 package which is lead(Pb)-freetv5嘉泰姆
