Voltages are selectable in 50mV steps within a range of 1.2V to 3.3V by operating from a 2V to 6V input. The CXLD6474includes two independent logic-controlled shutdown inputs and allows the output of each regulator to be turned off independently. When both outputs shutdown simultaneously, the chip will be turn off and consumes nearly zero operation current which is suitable for battery-power devices. The CXLD6474 includes high accuracy voltage reference, error amplifier, current limit circuit and output driver module.The CXLD6474 has excellent load and line transient response and good temperature characteristics,which can assure the stability of chip and power system.And It uses trimming technique to guarantee output voltage accuracy within ±1% or ±2%. The CXLD6474 is available in SOT-23-6 and ESOP-8 package which is Lead(Pb)-free 二.产品特点(Features) Up to 300mA Output Current(Each LDO) Dual Shutdown Pins Control Each Output 90uA Operating supply current per LDO Excellent Line regulation:0.05%/V Low Dropout:220mV@300mA High Power Supply Rejection Ratio Wide Operating Voltage Range:2.0V to 6.0V 1.2V to 3.3V Factory-Preset Output High Accuracy: ±1% or ±2% Internal Pulled down(8 M )resistor Current Limiting and Thermal Protection Two LDOs in SOT-23-6 and ESOP-8 Package RoHS Compliant and 100% Lead(Pb)-Free 三,应用范围 (Applications) Cellular and Smart Phones Battery-Powered Equipment Laptop, Palmtops, Notebook Computers Hand-Held Instruments PCMCIA Cards and Wireless LAN 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！ 五,产品封装图 (Package) 七,功能概述
