TS431中文资料低压可调分流器电压参考数据手册ST规格书

描述 Description

The TS431 is a low-voltage, three-terminal, adjustable shunt voltage reference. The output voltage can be set to any value between Vref (1.24 V) and 6 V using two external resistors. The TS431 is able to operate at a lower voltage (1.24 V) and lower cathode current than the widely-used TL431 and TL1431 shunt voltage reference. When driving an optocoupler, the TS431 is particularly suitable for regulating 3.3 V switching power supplies.

简介

TS431属于集成电路（IC）的电压基准。由制造生产的TS431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。
