一,产品概述(General Description) 
CXLD6493 is a series of low dropout three terminal regulators with a typical dropout
voltage of 1.4V at 3A load current.Other than fixed voltage versions (1.8V, 2.5V,3.3V, 5.0V),
CXLD6493 has an adjustable voltage version, with which desired voltage can be achieved
by setting the values of two external resistors of the application circuitry.CXLD6493 offers
thermal shut down and current limit functions to assure the stability of chip and power system.
