CXLD64142是一个3A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。CXLD64142/B集成了许多功能。上电复位（POR）电路监测VCNTL和车辆识别号引脚上的电源电压，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，内部设置延迟时间。它可以控制其他变换器的功率顺序。CXLD64142/B可由其他电源系统启用。拉动并保持EN/ENB电压低于0.4V，关闭/启用输出。

产品概述 返回TOP
The CXLD64142 is a 3A 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 CXLD64142/B integrates many functions. A Power-OnReset (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 the output voltage status with a delay time set internally. It can control other converter for power sequence. The CXLD64142/B can be enabled by other power systems. Pulling and holding the EN/ENB voltage below 0.4V shut/enable off the output. The CXLD64142 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.
