   产品概述 返回TOPz0p嘉泰姆

CXLD64240是</span>低静态电流、低噪声、高纹波抑制比的CMOS LDO稳压器，无需噪声旁路电容。该芯片具有高输出精度、超低压差、超低静态电流和快速启动等性能。CXLD64240在没有噪声旁路电容就能输出很低的噪声，非常适合于RF应用，尤其是适合于掌上型和电池供电的设备，CXLD64240提供使能控制引脚，引脚电压和TTL逻辑兼容，当使能关断芯片时，静态电流小于1uA，大大降低了待机功耗。另外关键的特性还包括有输出电流限制、过温关断及快速瞬态响应等。CXLD64240采用陶瓷电容就可以稳定的工作，采用SC-82小面积封装，这都可以大大节省电路板的面积。CXLD64240提供1.2V至3.6V各种输出电压版本。The CXLD64240 is an efficient CMOS low dropout (LDO) voltage regulator optimized for ultra-low-noise applications. It offers high output accuracy, extremely low dropout voltage, low ground current and fast start-up time. The CXLD64240 provides a very low noise output without a bypass capacitor, ideal for RF applications where a clean supply voltage source is required. Specifically designed for handheld and battery-powered devices, the CXLD64240 provides a TTL-logic-compatible enable pin. When the CXLD64240 is disabled, power consumption drops nearly to zero. Key features include current limit, thermal shutdown and faster transient response. The CXLD64240 works with low-ESR ceramic capacitors. Available in the SC-82 space saving package which reduces the amount of board space for power applications. The ECXLD64240offers wide fixed output voltage versions.
