CXLD64139是一个2A超低衰减线性稳压器。集成电路需要两个电源电压，一个是控制电路的控制电压（VCNTL），另一个是用于功率转换的主电源电压（VIN），以降低功耗并提供极低的压降。CXLD64139集成了许多功能。上电复位（POR）电路监测VCNTL和VIN引脚上的电源电压，以防止错误操作。热关机和电流限制功能可保护设备免受热过载和电流过载的影响。POK表示输出电压状态，内部设置了延迟时间。它可以控制其他变换器的功率顺序。CXLD64139可以由其他电源系统启用。拉并保持EN电压低于0.4V将关闭输出。

产品概述 返回TOP
The CXLD64139 is a 2A ultra low dropout linear regulator. The IC needs two supply voltages, one is a control voltage (VCNTL) for the control circuitry, the other is a main supply Voltage(VIN) for power conversion, to reduce power dissipation and provide extremely low dropout voltage. The CXLD64139 integrates many functions. A Power-On-Reset (POR) circuit monitors both supply voltages on VCNTL and VIN pins to prevent erroneous operations. The functions of thermal shutdown and current-limit protect the device against thermal and current over-loads. A POK indicates that the output voltage status with a delay time set internally. It can control other converter for power sequence. The CXLD64139 can be enabled by other power systems. Pulling and holding the EN voltage below 0.4V shuts off the output. The CXLD64139 is available in a SOP-8P package which features small size as SOP-8 and an Exposed Pad to reduce the junction-to-case resistance to extend power range of applications.
