一,产品概述(General Description)      75y嘉泰姆
75y嘉泰姆
   The CXLD64234 series is a 3A ultra low dropout linear regulator. This product is specifically75y嘉泰姆
designed to provide well supply voltage for front-side-bus termination on motherboards and75y嘉泰姆
NB applications. The IC needs two supply voltages, a control voltage for the circuitry and a75y嘉泰姆
main supply voltage for power conversion, to reduce power dissipation and provide extremely75y嘉泰姆
low dropout. The75y嘉泰姆
     CXLD64234 series integrates many functions. A Power-On-Reset (POR) circuit monitors both75y嘉泰姆
supply voltages to prevent wrong operations. A thermal shutdown and current limit functions75y嘉泰姆
protect the device against thermal and current over-loads. A POK indicates the output status with75y嘉泰姆
time delay which is set internally. It can control other converter for power sequence.75y嘉泰姆
   The CXLD64234 series can be enabled by other power system. Pulling and holding the EN pin75y嘉泰姆
below 0.4V shuts off the output.75y嘉泰姆
    The CXLD64234 series is available in DFN 3x3-10L & ESOP-8 package which features small size75y嘉泰姆
as SO-8 and anExposed Pad to reduce the junction-to-case resistance.75y嘉泰姆
