REF2940中文资料采用 3 引脚 SOT-23 封装的 4.096V、100ppm/°C、50µA 输入串联（带隙）电压基准数据手册TI规格书

描述 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.

特性 Features

• MicroSIZE Package: SOT-23
• Low Dropout: 1 mV
• High Output Current: 25 mA
• Low Temperature Drift: Maximum of 100 ppm/°C
• High Accuracy: 2%
• Low IQ: Maximum of 50 µA

简介

REF2940属于集成电路（IC）的电压基准。由TI制造生产的REF2940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。
