目录7.相关产品 产品概述 返回TOP The CXLD64137 is a 3A ultra low dropout linear regulator. This product is specifically designed to provide well supply volatage 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 CXLD64137 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 CXLD64137 is enabled by other power system. Pulling and holding the EN pin below 0.3V shuts off the output. The CXLD64137 is available in SOP-8P package which features small size as SOP-8 and an Exposed Pad to reduce the junction-to-case resistance, being applicable in 2~2.4W applications.产品特点 返回TOP · Ultra Low Dropout - 0.25V(typical) at 3A Output Current · Low ESR Output Capacitor (Multi-layer Chip Capacitors (MLCC)) Applicable · 0.8V Reference Voltage · High Output Accuracy - ±1.5% over Line, Load and Temperature · Fast Transient Response · Adjustable Output Voltage by External Resistors · Power-On-Reset Monitoring on Both VCNTL and VIN Pins · Internal Soft-Start · Current-Limit Protection · Under-Voltage Protection · Thermal Shutdown with Hysteresis · Power-OK Output with a Delay Time · Shutdown for Standby or Suspend Mode · Simple SOP-8P Package with Exposed Pad · Lead Free and Green Devices Available (RoHS Compliant) 应用范围 返回TOP · Front Side Bus VTT (1.2V/3A) · Note Book PC Applications · Motherboard Applications 技术规格书（产品PDF) 返回TOP 需要详细的PDF规格书请扫一扫微信联系我们，还可以获得免费样品以及技术支持！ 产品封装图 返回TOP
