Even in the event of large power supply variations, this ADR420BRZ 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 0.05%. This will operate at a maximum voltage of 18 V, making it easy to control the power in your circuit. To produce a constant current at your output, supply your circuit with a load regulation of 70ppm/mA and line regulation of 35ppm/V. This voltage reference circuit supports series topology. 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 3ppm/°C. This voltage reference circuit has an operating temperature range of -40 °C to 125 °C.
