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.
