REF192 - Low Dropout Voltage References

Download the REF192 datasheet PDF. This datasheet also covers the REF191 variant, as both devices belong to the same low dropout voltage references family and are provided as variant models within a single manufacturer datasheet.

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.
