【应用】国产负线性稳压器SGM2209助力数据采集器设计，最大500mA输出电流
在科技不断发展的今天，自动化在工业方面也逐渐成为了主流，以更高效率与更低人工成本为优势的自动化产线已经渗入了工业生产的每一个部分，因此，工业自动化设备数据采集和产品流程管理数据收集管理也被重视了起来。
国内一厂商在设计数据采集器的信号链部分的时候，选择使用运算放大器双电源供电的方案，需要用到负线性稳压器给高压运算放大器和模拟开关提供-8V的电压，而在选择负线性稳压器时，选择了圣邦微（SGMICRO）推出的高压输入，宽压输出的负线性稳压器SGM2209。
框图如下：
SGM2209在该应用中的优势：
1、宽输入/输出电压范围：-2.7V到-24V输入，-1.2V到-23V输出，适用于高压运算放大器供电需求；
2、最大500mA的输出电流，使其可以同时满足运算放大器和模拟开关的供电需求。
3、-40℃至+125℃工作温度范围，适用于大部分工业环境
