一,产品概述(General Description) osH嘉泰姆
osH嘉泰姆
The CXLD6474 dual, low noise, low-dropout regulator supplying up toosH嘉泰姆

300mA output current at each channel. The output voltage for each osH嘉泰姆

regulator is set independently by trimming. Voltages are selectableosH嘉泰姆

in 50mV steps within a range of 1.2V to 3.3V by operating from a 2V osH嘉泰姆

to 6V input. The CXLD6474includes two independent logic-controlled osH嘉泰姆

shutdown inputs and allows the output of each regulator to be turned osH嘉泰姆

off independently. When both outputs shutdown simultaneously, the osH嘉泰姆

chip will be turn off and consumes nearly zero operation current whichosH嘉泰姆

is suitable for battery-power devices.osH嘉泰姆

The CXLD6474 includes high accuracy voltage reference, error osH嘉泰姆

amplifier, current limit circuit and output driver module.The CXLD6474osH嘉泰姆

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

characteristics,which can assure the stability of chip and power osH嘉泰姆

system.And It uses trimming technique to guarantee output voltage osH嘉泰姆

accuracy within ±1% or ±2%. The CXLD6474 is available in SOT-23-6 andosH嘉泰姆

ESOP-8 package which is Lead(Pb)-free osH嘉泰姆
