REF3012, REF3020, REF3025, REF3030, REF3033, REF3040 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 Acc.

Table 2. ABSOLUTE MAXIMUM RATINGS (Note 2) Rating Value Unit VIN Storage Temperature Range 6.5 V −55 to +125 _C Junction Temperature Range +150 _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. Table 3.
