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.
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
• SOT−23 3−Lead Package • This Device is Pb−Free, Halogen Free/BFR Free, and RoHS
Compliant
Typical Applications
• Battery Powered Systems • A/D and D/A Converters • Precision Regulator Systems • Power Supplies • Portable Medical Equipment

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.
