Description
General part information
REF2940 Series
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 make it ideal for portable and battery-powered applications. The REF29xx does not require a load capacitor, but it is stable with any capacitive load.
Unloaded, the REF29xx can be operated with supplies within 1 mV of output voltage. All models are specified for the wide temperature range, –40°C to 125°C.
