产品简述:
R1172x是一款基于cmos的正稳压IC,专门为汽车应用设计。R1172x具有超低输出电流,1A输出电流能力的特点。即使输出电压设置为1.5V,内部场效应管的电阻通常为0.32Ω。因此,R1172x适用于需要大电流和小滴电流的应用。可接受低输入电压,可设置低输出电压。
最小输入电压为1.4V,最低设定输出电压为0.8V。每一个集成电路都由电压参考单元、误差放大器、用于设置输出电压的电阻网、过流限流电路、芯片使能电路、热关闭电路等组成。芯片使能脚可实现超低功耗电流的待机模式。R1172的输出电压固定在IC中。
由于该IC的封装是SOT-23-5、SOT-89-5和HSOP-6J,具有较高的功耗,因此IC可以高密度安装在单板上。
应用程序:
笔记本电脑的本地电源。
便携式通讯设备、照相机、录像机的本地电源。
家用电器的本地电源。
