一,产品概述(General Description)      

   The CXLD64234 series is a 3A ultra low dropout linear regulator. This product is specifically
designed to provide well supply voltage for front-side-bus termination on motherboards and
NB applications. The IC needs two supply voltages, a control voltage for the circuitry and a
main supply voltage for power conversion, to reduce power dissipation and provide extremely
low dropout. The
     CXLD64234 series integrates many functions. A Power-On-Reset (POR) circuit monitors both
supply voltages to prevent wrong operations. A thermal shutdown and current limit functions
protect the device against thermal and current over-loads. A POK indicates the output status with
time delay which is set internally. It can control other converter for power sequence.
   The CXLD64234 series can be enabled by other power system. Pulling and holding the EN pin
below 0.4V shuts off the output.
    The CXLD64234 series is available in DFN 3x3-10L & ESOP-8 package which features small size
as SO-8 and anExposed Pad to reduce the junction-to-case resistance.
