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 (120

µA 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.
