一,产品概述(General Description) 7wP嘉泰姆
7wP嘉泰姆
CXLD6475 dual, low-noise, low-dropout regulator delivers 7wP嘉泰姆

at least 300mA of continuous output current. The output voltage7wP嘉泰姆

for each regulator is set independently by trimming. Output 7wP嘉泰姆

voltages are selectable in 100mV steps within a range of 1.2V7wP嘉泰姆

to 3.5V.Typical output noise is 47uVrms, and PSRR is 73dB at 7wP嘉泰姆

100Hz. The CXLD6475 includes two independent logic-7wP嘉泰姆

controlled shutdown inputs and allows the output of each 7wP嘉泰姆

regulator to be turned of independently.7wP嘉泰姆

CXLD6475 includes high accuracy voltage reference, error7wP嘉泰姆

amplifier, current limit circuit and output driver module CXLD64757wP嘉泰姆

has excellent load and line transient response and good 7wP嘉泰姆

temperature characteristics, which can assure the stability of chip7wP嘉泰姆

and power system. And it uses trimming technique to guarantee 7wP嘉泰姆

output voltage accuracy within±2%.7wP嘉泰姆

CXLD6475 is available in SOT-23-6 package which is lead(Pb)-free7wP嘉泰姆
