REF191 - Low Dropout Voltage References

General Description

The REF19x series precision band gap voltage references use a patented temperature drift curvature correction circuit and laser trimming of highly stable, thin-film resistors to achieve a very low temperature coefficient and high initial accuracy.

Key Features

  • Temperature coefficient: 5 ppm/°C maximum High output current: 30 mA Low supply current: 45 μA maximum Initial accuracy: ±2 mV maximum1 Sleep mode: 15 μA maximum Low dropout voltage Load regulation: 4 ppm/mA Line regulation: 4 ppm/V Short-circuit protection.
