ZR431中文资料2-5v-reference-voltage-s数据手册Diodes规格书

描述 Description

The ZR431 is a three terminal adjustable shunt regulator offering excellent
temperature stability and output current handling capability up to 100mA. The output voltage may be set to any chosen voltage
between 2.5 and 20 volts by selection of two external divider resistors.
The devices can be used as a replacement for zener diodes in many applications
requiring an improvement in zener performance.

简介

ZR431属于集成电路（IC）的电压基准。由制造生产的ZR431电压基准产品属于基准电压源系列，可通过相对较不稳定的电源提供稳定的电势，电压值始终保持恒定，以便在测量、控制和类似应用中用作比较的标准。其功能行为可能与用于大功率调节的线性稳压器相似，但基准电压源器件却不适合用于此类用途。用作比较标准时，若输出电流容量或实际负载电流增大，其性能通常会降低。
