3 Description
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.
