一,产品概述(General Description) 
The CXLD64231 series are low dropout, positive linear regulators with very low
quiescent current.
The CXLD64231 can supply 300mA output current with a low dropout voltage& very
low output voltage.
The CXLD64231 regulator is able to operate with output capacitors as small as 1μF to
10μF for stability. Other than the current limit protection CXLD64231 also offers on chip
thermal shutdown feature providing protection against overload or any condition
when the ambient temperature exceeds the junction temperature.
The CXLD64231 series are available in low-profile, space-saving SOT-23-5L,
SOT-23-5LR & SC-70-5L packages.
