ON Semiconductor's CAT8900 family provide a highly accurate voltage reference, with initial accuracy as high as 0.02 percent [± 0.5 millivolts (mV)] and a stable, 20 parts per million per degrees Celsius (ppm/ºC) temperature coefficient.

Current consumption is 800nA. 

The CAT8900 family offers nine voltage reference choices:  1.024 volts (V), 1.200 V, 1.250 V, 1.800 V, 2.048 V, 2.500 V, 2.600 V, 3.000 V and 3.300 V.  Custom voltages are available on request. 

Each reference is available in four accuracy grades:  ±0.5 mV, ±1.0 mV, ±2.5 mV and ±5.0 mV.  The devices source or sink up to 10mA of load current with as little as 50 mV of dropout. In most applications they do not require an output bypass capacitor. 

The precision voltage references come in a Pb-free, RoHS-compliant, 3-lead SOT-23 package.
