【应用】圣邦微大电流负线性稳压器SGM2209助力多路数字可调电源设计，输入电压-2.7~-24V
在如今的仪器内部电源设计与工业生产中，越来越多的人选择使用数字可调电源来实现内部各模块的供电需求，这种可以根据需求实时调节输出电压的电源模式也更多被设计在产品中了。
国内一厂商在选择运放的负压供电方案时，选择了电荷泵加负线性稳压器的方案，需要5V转-5V的电荷泵，后续-5V给到负线性稳压器转到-3.3V，负线性稳压器客户选择了圣邦微这款SGM2209-ADJXTDB8G/TR。
框图如下：
SGM2209-ADJXTDB8G/TR在该应用中的优势：
1、最大500mA的输出电流，满足后端负载的供电需求
2、工作输入电压范围-2.7V至-24V，满足应用中-5V降至-3.3V的需求
3、-40℃至+125℃的宽工作温度范围，满足整个系统不同的工作场合
综上所述，SGMICRO的负线性稳压器SGM2209-ADJXTDB8G/TR非常适合应用于多路数字可调电源设计。

【应用】国产负压线性稳压器SGM2209助力工业相机电源设计，具有噪声低、PSRR数值高等优势
在工业相机设计中，当采用开关稳压器时，由于电感器要求使用额外的区域，因此开关稳压器形状因数较大。必须考虑稳压器开关频率与测量信号频率之间的关系。为了减小开关噪声引入的电源干扰，往往会在开关电源的后级增加一个高PSRR、低噪声的LDO稳压器来保证供电的稳定性。本文推荐采用圣邦微电子旗下的SGM2209是一款高性能的负压LDO，采用NMOS工艺，内置-1.2V高精度基准。
