CXLD64248瞬态响应快高PSRR大负载电流的低漏失线性调整器输出精度高漏失电压小低静态电流和快速启动的特点.

CXLD64248是一款瞬态响应快、高PSRR、大负载电流的低漏失线性调整器。它具有输出精度高，漏失电压小，低静态电流和快速启动的特点.CXLD64248可工作于低ESR的陶瓷电容下，从而节约了实际应用中PCB板面积。CXLD64248的全负载工作仅需要2.2uF的陶瓷电容就可以保证稳定性。当CXLD64248检测到故障信号，例如过温关断信号时，芯片会关断功率管并将VOUT通过内部放电电阻放电止地。CXLD64248通过外部反馈电阻实现输出可调，当FB pin被连接至两个外部电压分压端时，它的输出可调，可调电压的范围为0.8V到5V。其他的关键特性还包括过流保护，过温关断。CXLD64248的封装为SOT23-5。The CXLD64248 is a high current, low dropout linear regulator with fast transient response and high PSRR. It offers high output accuracy, extremely low dropout voltage, low quiescent current and fast start-up time. The CXLD64248 is designed to work with low-ESR ceramic capacitor, reducing the amount of the PCB area necessary for power applications. Only a 2.2μF ceramic capacitor can make the device stable over the whole load range. When CXLD64248 detects fault signal, such as over-temperature, it will turn off the pass transistor and discharge VOUT to GND from the internal resistor. The CXLD64248 works at ADJ mode. When FB pin is connected to two external resistors divider, its output can be adjusted from 0.8V to 5V. Other key features include over-current protection, thermal shutdown. The device can be available in the SOT23-5 package.
