Even in the event of large power supply variations, this REF195GSZ voltage reference power management device from Analog Devices can produce and maintain a precise DC voltage. It has an initial accuracy of 2mV. With an output that has a voltage of 5 V, this is power management at its best. The best way to provide power to your application is by using this, which needs a voltage lower than 18 V. At a load regulation of 8ppm/mA and line regulation of 8ppm/V your circuit is capable of maintaining a constant voltage level at your output. 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 25ppm/°C. This voltage reference circuit has an operating temperature range of -40 °C to 85 °C.
