Even in the event of large power supply variations, this ADR441ARMZ voltage reference power management device from Analog Devices can produce and maintain a precise DC voltage. With an output that has a voltage of 2.5 V, this is power management at its best. With a voltage no larger than 20 V, this will supply sufficient power to your circuit. It has an initial accuracy of 0.13%. Users like the load regulation of 50ppm/mA and line regulation of 20ppm/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. This voltage reference circuit has an operating temperature range of -40 °C to 125 °C. It runs with a maximum temperature coefficient of 10ppm/°C.
