Even in the event of large power supply variations, this LT1009CLP voltage reference power management device from Texas Instruments can produce and maintain a precise DC voltage. It has an initial accuracy of 0.2%. With an output that has a voltage of 2.5 V, this is power management at its best. Using a load regulation of 10mV is needed for a programmable DC power supply. This voltage reference circuit supports shunt topology. This product comes packaged in bulk, so the parts will be stored loosely. This voltage reference circuit has a minimum operating temperature of 0 °C and a maximum of 70 °C. It runs with a maximum temperature coefficient of 25ppm/°C.
