CXLD64117是一种低压差线性稳压器，它只需要一个2.8-6V的输入电压源，就可以将高达300mA的电流输出到设定的输出电压。它可以与低ESR陶瓷电容器配合使用，使其成为笔记本电脑和手机等电池供电应用的理想选择。在300毫安的负载下，它的典型电压降只有230毫伏。CXLD64117提供两种输出电压操作模式：固定输出电压模式和可调输出电压，由设置输出电压的设定引脚控制。

产品概述 返回TOP
The CXLD64117 is a low dropout linear regulator which only needs a single input voltage supply from 2.8 to 6V, and it can deliver current up to 300mA to a set output voltage. It can work with low ESR ceramic capacitors that make it ideal for using in the battery-powered applications, such as notebook computers and cellular phones. Its typical dropout voltage is only 230mV at 300mA loading. The CXLD64117 provides two output voltage operation modes, the fixed output voltage mode and the adjustable output voltage, controlled by the SET pin for setting the output voltage. The fixed output voltage mode sets the output to a preset voltage (only 1.2V available now) in the chip by connecting SET pin to the ground, and the adjustable output voltage mode needs two resistors as a voltage divider connected to SET pin to define the output. The current-limit with current foldback and thermal shutdown functions protect the device against current over-loads and over temperature. The CXLD64117 is available in a SOT- 23-5 package.
