REF2912 描述

The REF29xx is a precision, low-power, low-voltage dropout voltage reference family available in a tiny SOT23-3.

The REF29xx’s small size and low power consumption (50uA max) make it ideal for portable and battery-powered applications. The REF29xx does not require a load capacitor, but is stable with any capacitive load.

Unloaded, the REF29xx can be operated with supplies within 1mV of output voltage. All models are specified for the wide temperature range, –40°C to +125°C.
