The CXLD6471 performance is optimized for battery-powered systems to deliver ultra low noise and low quiescent current. A noise bypass pin is available for further reduction of output noise.Regulator ground current increases only slightly in dropout, further prolonging the battery life. The CXLD6471 also works with low-ESR ceramic capacitors, reducing the amount of board space necessary for power applications, critical in hand-held wireless devices. The CXLD6471 consumes less than 0.01 μA in shutdown mode and has fast turn-on time less than 50μs. The other features include ultra low dropout voltage, high output accuracy, current limiting protection, and high ripple rejection ratio. Available in the 5-lead of SC-70, SOT-23 packages. 二.产品特点(Features) Ultra-low Noise for RF Application Ultra-Fast Response in Line/Load Transient Quick Start-Up (Typically 50μS) <0.01μA Standby Current When Shutdown. Low Dropout:210mV@300mA Wide Operating Voltage Ranges:2V to 6V TTL-logic-Controlled Shutdown Input Low Temperature Coefficient Current Limiting Protection Thermal Shutdown Protection Only 1μF Output Capacitor Required for Stability High Power Supply Rejection Ratio Custom Voltage Available Fast output discharge Available in 5-Lead SOT-23 and SC-70 Package 三,应用范围 (Applications) Cellular and Smart Phones Battery-Powered Equipment Laptop, Palmtops,Notebook Computers Hand-Held Instruments PCMCIA Cards MP3/MP4/MP5 Players Portable Information Appliances 四.技术规格书下载(产品PDF) 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!
