The REF29xx is a precision, low-power, low-voltage dropout voltage reference family available in a tiny 3‑pin SOT-23 package. The small size and low power consumption (50 µA maximum) of the REF29xx is an excellent option for portable and sensor applications. The REF29xx is stable with any capacitive load and does not require a load capacitor. The REF29xx is operable unloaded with supplies within 1 mV of output voltage. All models are specified for the wide temperature range of –40°C to 125°C.
