REF3130AIDBZR集成电路（IC）的电压基准规格书PDF中文资料

REF3130AIDBZR属于集成电路（IC）的电压基准。由德州仪器制造生产的REF3130AIDBZR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 REF31xx is a family of precision, low power, low

dropout, series voltage references available in the

tiny 3-pin SOT-23 package.

The REF31xx's small size and low power

consumption (100 μA typical) make it ideal for

portable and battery-powered applications. The

REF31xx does not require a load capacitor, but is

stable with any capacitive load and can sink or

source up to 10 mA of output current.

Unloaded, the REF31xx can operate on supplies

down to 5 mV above the output voltage. All models

are specified for the wide temperature range of –40°C

to +125°C.
