Even in the event of large power supply variations, this REF191ESZ voltage reference power management device from Analog Devices can produce and maintain a precise DC voltage. With an output that has a voltage of 2.048 V, this is power management at its best. It has an initial accuracy of 2mV. With a voltage no larger than 18 V, this will supply sufficient power to your circuit. This voltage reference circuit supports series topology. A load regulation of 10ppm/mA and line regulation of 4ppm/V is necessary for providing a constant voltage level at your output. In order to ensure parts aren't damaged by bulk packaging, this product comes in tube packaging to add a little more protection by storing the loose parts in an outer tube. It runs with a maximum temperature coefficient of 5ppm/°C. This voltage reference circuit has an operating temperature range of -40 °C to 85 °C.
