REF3220中文资料2.048V、4ppm/°C、100µA、6 引脚 SOT-23 串联（带隙）电压基准数据手册TI规格书

描述 Description

The REF32xx is a very low drift, micropower, low-dropout, precision voltage reference family available in the tiny SOT23-6 package. The small size and low power consumption (120&micr;A max) of the REF32xx make it ideal for portable and battery-powered applications. This reference is stable with any capacitive load. The REF32xx can be operated from a supply as low as 5mV above the output voltage, under no load conditions. All models are specified for the wide temperature range of –40°C to +125°C.

特性 Features

• Excellent Specified Drift Performance:
• 7ppm/°C (max) at 0°C to +125°C
• 20ppm/°C (max) at –40°C to +125°C

• Microsize Package: SOT23-6
• High Output Current: ±10mA
• High Accuracy: 0.01%
• Low Quiescent Current: 100µA
• Low Dropout: 5mV

简介

REF3220属于集成电路（IC）的电压基准。由TI制造生产的REF3220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。
