目录7.相关产品 产品概述 返回TOP CXLD64252是一款瞬态回应快、高PSRR、大负载电流的低漏失线性调整器。它具有输出精度高，漏失电压很小，低静态电流和快速启动的特点。CXLD64252可以在低ESR的陶瓷电容下工作，从而节约了实际应用中PCB板的面积。CXLD64252在全负载工作下仅需要2.2uF的陶瓷电容就可以保证稳定性。当CXLD64252检测到故障信号，例如过温关断信号时，芯片会关断功率管并将VOUT通过内部电阻放电止地。CXLD64252为内部固定输出电压，内部输出电压的范围从0.8V到3.6V。其它的关键特性还包括过流保护，过温关断。CXLD64252可应用于SOT23-5的封装。The CXLD64252 is a high current, low dropout linear regulator with fast transient response and high PSRR. It offers high output accuracy, extremely low dropout voltage, low quiescent current and fast start-up time. The CXLD64252 is designed to work with low-ESR ceramic capacitor, reducing the amount of the PCB area necessary for power applications. Only a 2.2μF ceramic capacitor can make the device stable over the whole load range. When CXLD64252 detects fault signal, such as over-temperature, it will turn off the pass transistor and discharge VOUT to GND from the internal resistor. CXLD64252 only can be operated in fixed mode, the pre-set valve is from 0.8V~3.6V. Other key features include over-current protection, thermal shutdown. The device can be available in the SOT23-5 package.产品特点 返回TOP •2.5V到5.5V的输入电压范围 •300mV@600mA的漏失电压 •超快速的瞬态响应 •2.2μF的陶瓷输出电容 •PSRR在1kHz时为70dB •120μA的静态电流 •关断电流小于1μA •输出电流限制 高精度的输出电压：2%的内部精度 固定输出电压的范围：0.8V~3.6V •热关断 •关断时可对输出电容自动放电 •符合RoHS标准，并且100%无铅和无卤素 2.5V to 5.5V Input Voltage Range 300mV@600mA Dropout Voltage Ultra Fast Transient Response Stable with 2.2μF Ceramic Output Capacitor 70dB PSRR at 1kHz Low 120μA Quiescent Current Low Shutdown Current:<1μA Output Current Limit Output Voltage With High Accuracy: 2% Initial Accuracy Fixed Output Voltage: 0.8V ~ 3.6V Thermal Shutdown COUT Auto-Discharge when Shutdown RoHS Compliant and 100% Lead (Fb)-Free Halogen-Free 应用范围 返回TOP •无线网络模块 •电池供电装置 •笔记本计算机 WiFi Modules Battery-Powered Equipment Notebook Computers 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 a 电路原理图 返回TOP
