概览
NCP431集成电路是三端子可编程分路稳压器二极管。这是行业标准TL431A 的直接升级版。这款单片集成电路电压基准能够作为低温度系数齐纳运行，配合两个外部电阻可编程范围为Vref至36V。这类器件具有40 µA至100mA的宽运行电流范围，典型动态阻抗为0.22Ω。这类电压基准的特性使其在很多应用中成为齐纳二极管的绝佳替代产品，如数字电压计、电源和运算放大器电路。2.5V基准使其能够从5.0V逻辑电源中方便地获得稳定的基准。由于NCP431作为分路稳压器运行，所以既可用作正电压基准也可用作负电压基准。较低的最小运行电流使这款器件成为SMPS适配器中的次级稳压器的绝佳选择，无负载功耗极低。
NCP432与NCP431的各项功能和电气规格完全相同，仅引脚配置不同。
