REF191-EP Low Dropout Voltage Reference

The REF191-EP precision band gap voltage reference uses a proprietary 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. The REF191-EP is a micropower, low dropout voltage de.
