CXLD64245/A是低静态电流、低噪声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、高PSRR和快速启动等性能。</span>CXLD64245/A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,尤其是适合于手持式和电池供电的设备,</span>CXLD64245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。</span>CXLD64245/A采用陶瓷电容就可以稳定的工作,采用SOT23-3或SOT23-5小面积封装,可以大大节省电路板的面积。</span>CXLD64245/A提供1.2V至3.6V各种输出电压版本The CXLD64245/A 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 CXLD64245/A 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 CXLD64245/A provides a TTL-logic-compatible enable pin. When theCXLD64245/A is disabled, power consumption drops nearly to zero. Key features include current limit, thermal shutdown and faster transient response. The CXLD64245A works with low-ESR ceramic capacitors. Available in the SOT23-3 or SOT23-5 space saving package which reduces the amount of board space necessary for power applications. TheCXLD64245A offers wide fixed output voltage versions.
