REF3125中文资料采用 3 引脚 SOT-23 封装的 2.5V、20ppm/°C（最大值）、100µA 串联电压基准数据手册TI规格书

描述 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.

特性 Features

• Size Package: SOT23-3
• Low Dropout: 5 mV
• High Output Current: ±10 mA
• High Accuracy: 0.2% Maximum
• Low IQ: 115 µA Maximum
• Excellent Specified Drift Performance:
• 15 ppm/°C (Maximum) from 0°C to +70°C
• 20 ppm/°C (Maximum) from –40°C to +125°C

简介

REF3125属于集成电路（IC）的电压基准。由TI制造生产的REF3125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。
