300mA, High PSRR Low-Noise LDO超低噪声优化设计的高效CMOS线性稳压器CXLD64242电流限制过温关断保护和快速瞬态响应集成电路电子元器件

   产品概述 返回TOPD3d嘉泰姆

CXLD64242是</span>一款为超低噪声优化设计的高效CMOS线性稳压器，它还具有高输出精度、极低压差、低静态电流和快速启动等特性。CXLD64242输出很低的噪声电压，应用于需要干净电压源的RF电路是非常理想的，一个旁路噪声的引脚可以用来大大地降低输出噪声。 这款器件为手持式和电池供电的设备特别设计，它提供了与TTL逻辑兼容的使能控制引脚，当使能关断时，功耗下降至几乎为零。CXLD64242采用5引脚SC-70封装，它可以在使用低ESR的陶瓷电容时正常工作，大大节省了PCB板空间，这对手持式无线设备是非常重要的。CXLD64242能提供很宽范围的输出电压。关键特性还包括电流限制、过温关断保护和快速瞬态响应。The CXLD64242 is an efficient, CMOS 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 CXLD64242 provides a very low noise output, ideal for RF applications where a clean voltage source is required. A noise bypass pin is also available for further reduction of output noise. Designed specifically for handheld and batterypowered devices, the CXLD64242 provides a TTL-logic-compatible enable pin. When disabled, power consumption drops nearly to zero. The CXLD64242 also works with low-ESR ceramic capacitors, reducing the amount of board space necessary for power applications, critical in handheld wireless devices. Available in the SC-70 and SOT23-5 package, the CXLD64242 offers a wide range of output voltages. Key features include current limit, thermal shutdown and faster transient response.
