Even in the event of large power supply variations, this LT1009ID voltage reference power management device from Texas Instruments 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. It has an initial accuracy of 0.2%. This voltage reference circuit supports shunt topology. Operate at a constant current by utilizing the load regulation of 6mV. 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 35ppm/°C. This voltage reference circuit has an operating temperature range of -40 °C to 85 °C.
