目录7.相关产品 产品概述 返回TOP CXLD64240是低静态电流、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.产品特点 返回TOP • 2.5V to 5.5V输入电压范围 • 30μV(rms)输出噪声电压 • 低压差90mV @150mA • 高PSRR 70dB@1kHz • 30uA超低静态电流 • 保证150mA输出电流 • 输出采用陶瓷电容就可稳定工作 • 优质的负载和电源瞬态响应 • 过温关断和电流限制保护 • 1.2V至3.6V范围50mV步进的输出电压 • 节省空间的4引脚SC-82封装 • 符合RoHS规范及100% Pb-Free z 2.5V to 5.5V Input Voltage Range z 30μV(rms) Output Noise z 90mV Dropout @ 150mA z 70dB PSRR at 1kHz No Bypass Capacitor z Low 30μA Ground Current z Guaranteed 150mA Output Current z Stable with a 1μF Ceramic Output Capacitor when VOUT ≥ 1.5V, or 2.2μF when VOUT<1.5V z Excellent Load/Line Transient z Thermal Shutdown and Current Limit Protection z Available 1.2V to 3.6V Fixed Output Voltages (50mV increments) z Space-Saving 4-pin SC-82 Package z RoHS Compliant and 100% Lead (Pb)-Free 应用范围 返回TOP • 蜂窝式电话 • 相机模组 • PDA和掌上型电脑 • 个人消费电子产品 z Cellular Phones z Camera Modules z PDA and Palmtop Computers z Consumer/Personal Electronics 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!
