ADP1740:  2A、低输入电压LDO线性稳压器

Product Description

ADP1740/ADP1741 是CMOS低压差线性稳压器，工作电压范围为1.6V至3.6V，能够提供高达2A的输出电流。这些低输入输出的LDO是I/O电压轨为2.5V至.8V、内核电压低至0.75V的纳米级工艺FPGA的理想选择。。ADP1740/ADP1741采用先进的专用架构，能够提供很高的电源抑制比和低噪声，并且实现了出色的电源和负载瞬态响应，只需一只很小的4.7μF陶瓷输出电容器即可工作。

ADP1740提供7个可选的固定输出电压。 ADP1741 为输出电压可调稳压器，通过一个外接分压器，可提供0.75V至3.0V范围内的任意输出电压。这两款器件都支持外接一个软启动电容器实现编程启动控制。

该器件具有一个“电源正常”输出引脚，允许电源系统以数字检查的方式来监控输出电压轨是否正常。ADP1740/ADP1741采用16引脚的4mm×4mm LFCSP封装，外形尺寸非常紧凑，能以很小的体积和电路板为需要高达2A输出电流的应用提供出色的散热性能。
