DESCRIPTION
The REF32xx is a very low drift, micropower, low-dropout,
precision voltage reference family available in the tiny
SOT23-6 package.
The small size and low power consumption (120µA max)
of the REF32xx make it ideal for portable and
battery-powered applications. This reference is stable with
any capacitive load.
The REF32xx can be operated from a supply as low as
5mV above the output voltage, under no load conditions.
All models are specified for the wide temperature range of
−40°C to +125°C.
