REF3220 采用 SOT23-6 封装的 2.048V 输出 4ppm/C 漂移 100uA 系列（带隙）电压参考

REF3220 描述

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 (120µA 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.
