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 spacesaving SOT23 package, and for most
applications can forgo the use of an output bypass capacitor.
Features
Reference Voltages:
1.25 V, 2.048 V, 2.5 V, 3.0 V, 3.3 V, 4.096 V
High Accuracy: ±0.2%
Low Quiescent Current: 30 mA max
High Output Current: 10 mA Sourced or Sunk
Maximum 50 ppm/°C Temperature Drift over the Specified Range of
40°C to +85°C

Stresses exceeding Maximum Ratings may damage the device. Maximum Ratings are stress ratings only. Functional operation above the
Recommended Operating Conditions is not implied. Extended exposure to stresses above the Recommended Operating Conditions may affect
device reliability.
2. Maximum terminal current is bounded by the maximum current handling of the switches, maximum power dissipation of the package.
