REF2930AIDBZT集成电路（IC）的电压基准规格书PDF中文资料

REF2930AIDBZT属于集成电路（IC）的电压基准。由德州仪器制造生产的REF2930AIDBZT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 REF29xx is a precision, low-power, low-voltage

dropout voltage reference family available in a tiny

3‑pin SOT-23 package.

The small size and low power consumption (50 μA

maximum) of the REF29xx make it ideal for portable

and battery-powered applications. The REF29xx does

not require a load capacitor, but it is stable with any

capacitive load.

Unloaded, the REF29xx can be operated with

supplies within 1 mV of output voltage. All models are

specified for the wide temperature range, –40°C to

125°C.
