一,产品概述(General Description) 
The CXLD64227 is an efficient, precise dual-channel CMOS LDO regulator optimized for
ultra-low-quiescent applications.Regulators output1 and output2 are capable of sourcing
600mA of output current. The regulators are stable with output capacitors as low as 1uF,
including current limit, thermal shutdown protection, fast transient response, low dropout
voltage, high output accuracy, current limiting protection, and high ripple rejection ratio.
The CXLD64227 regulators are able to support individual On/Off function.
The CXLD64227 regulators are available in used ESOP-8 package.
