产品描述

NSREF30/31xx，NSREF30/31xxQ 系列包含 NSREF30xx，NSREF31xx，NSREF30xxQ，NSREF31xxQ 四个子系列，采用小巧的 3 引脚 SOT23 封装，能提供 0.2% 初始精度，NSREF30xx 的温漂为 10ppm/℃典型值，35ppm/℃最大值，而 NSREF31xx 的温漂为 5ppm/℃典型值，15ppm/℃最大值。

NSREF30/31xx 采用先进的工艺及专门的低噪声设计，在 2.5V 时仅输出 20uVpp( 典型值 ) 的噪声。NSREF30/31xx 仅要求输入电压比输出电压高 1mV 即可正常输出 工作电压 ( 除 NSREF3012/3112 需要最低 1.8V 工作电压 )，对电源电压可能会降低的场景非常友好，NSREF30/31xx 对输出端电容不作要求。不接输出电容也可以正常工作，外接电容值可支持 10uF, 拓展了其应用的边界条件。 其中每个子系列可分为 6 个不同型号，分别对应不同其不同输出电压。各产品均有车规和工规型号，其中车规级别产品满足 AEC-Q100 Grade1 的 可靠性要求，可在 -40~125℃的严苛环境下胜任工作。

Description

The NSREF30/31xx，NSREF30/31xxQ is a family of precision, low power, low dropout, series voltage references available in the tiny 3-pin SOT-23 package. The NSREF30XX offers 0.2% initial accuracy, 35 ppm/°C maxim tempco. The NSREF31XX offers 0.2% initial accuracy, 15 ppm/°C maxim tempco.

The NSREF30/31xx，NSREF30/31xxQ does not require a load capacitor,yet is stable with capacitive loads and load and can sink or source up to ±10 mA of output current, can operate on supplies down to 1 mV above the output voltage. and output only 20uVpp noise(2.5V version), and consume only 130uA. All devices are specified for the wide temperature range of -40°C to +125°C, and could offer both industry and auto grade versions.

The NSREF30/31xx，NSREF30/31xxQ family is commonly used in solar invert, digital power, industry sensor, control system and portable batery power system.
