REF3030 采用 SOT23-3 封装的 3.0V 输出 50ppm/℃ 漂移 50uA 静态电流的（带隙）电压参考系列

REF3030 描述

The REF30xx is a precision, low power, low voltage dropout voltage reference family available in a tiny SOT23-3.

The REF30xx small size and low power consumption (50uA max) make it ideal for portable and battery-powered applications. The REF30xx does not require a load capacitor, but is stable with any capacitive load.

Unloaded, the REF30xx can be operated with supplies within 1mV of output voltage. All models are specified for the wide temperature range, –40°C to +125°C.
