High Precision, Low Drift,

CMOS Voltage Reference

The REF30xx family of voltage references provides accurate

voltage regulation with a maximum temperature drift of 50 ppm/

°C.

The REF30xx can source or sink up to 10 mA of load current. It is

supplied in a space−saving SOT−23 package, and for most

applications can forgo the use of an output bypass capacitor.
