一,产品概述(General Description) 
CXLD6465 series is a group of positive voltage output, low power consumption,
low dropout voltage, three terminal regulator. It can provide 200mA output current
when input / output voltage differential drops to 420mV （ Vout=3.3V）, And it also
provides foldback short-circuit protection and output current limit function. The
very low power consumption of CXLD6465（Iq=2.0uA）can greatly improve
natural life of batteries.
CXLD6465 can provide output value in the range of 1.1V~5.0V in 0.1V steps. It also
can customized on command.CXLD6465 includes high accuracy voltage reference,
error amplifier, current limit circuit and output driver module.
CXLD6465 has well load transient response and good temperature characteristic, And
it uses trimming technique to guarantee output voltage accuracy within±2%.
