目录 1.产品概述 2.产品特点 3.应用范围 4.技术规格书下载（PDF文档） 一.产品概述 The CXLD6446 series are highly accurate, low noise, CMOS LDO Voltage Regulators. Offering low output noise, high ripple rejection ratio, low dropout and very fast turn-on times, the CXLD6446 series is ideal for today’s cutting edge mobile phone. Internally the CXLD6446 includes a reference voltage source, error amplifiers, driver transistors, current limiters and phase compensators. The CXLD6446s current limiters' foldback circuit also operates as a short protect for the output current limiter and. the output pin. The CXLD6446series is also fully compatible with low ESR ceramic capacitors, reducing cost and improving output stability. This high level of output stability is maintained even during frequent load fluctuations, due to the excellent transient response performance and high PSRR achieved across a broad range of frequencies.The CE function allows the output of regulator to be turned off, resulting in greatly reduced power consumption. 二.产品特点 Maximum Output Current: 500mA （VIN＝4.3V,VOUT＝3.3V） Dropout Voltage: 100mV@ IOUT =100mA Operating Voltage Range: 2V～6.0V Highly Accuracy: ±2％ Low Power Consumption: 40uA（TYP.） Standby Current: 0.1uA（TPY.） High Ripple Rejection: 70dB@1KHz （CXLD6446C33） Low output noise: 50uVrms Line Regulation: 0.05％（TYP.） Ultra Small Packages: SOT-89-3，SOT-23-3， SOT-23-5, DFN6L, SOT-353 三.应用范围 Mobile phones Cordless phones, radio communication equipment Portable games Cameras, Video cameras Reference voltage sources Battery powered equipment 四.技术规格书（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
