REF3040集成电路（IC）的电压基准规格书PDF中文资料

REF3040属于集成电路（IC）的电压基准。由德州仪器制造生产的REF3040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。

3 Description

The REF30 is a precision, low-power, low-dropout

voltage, reference family available in a tiny 3-

pin SOT-23 package. REF30E is the enhanced

performance version of REF30 family which is

designed for precision applications. The REF30E

offers improved temperature drift and initial accuracy

while operating at a lower quiescent current of 25μA.

The low power consumption and the improved

precision make the REF30E very attractive for looppowered

industrial applications such as pressure

and temperature transmitter and battery-powered

applications. The REF30/REF30E is specified over

the extended industrial temperature range of –40°C to

+125°C. The REF30 is easy to use in intrinsically safe

and explosion-proof applications because the REF30

does not require a load capacitor to be stable.
