Texas InstrumentsLM385D-1-2电压参考

Even in the event of large power supply variations, this LM385D-1-2 voltage reference power management device from Texas Instruments can produce and maintain a precise DC voltage. With an output that has a voltage of 1.235 V, this is power management at its best. It has an initial accuracy of 2%. This voltage reference circuit supports shunt topology. At a load regulation of 20mV your circuit is capable of maintaining a constant voltage level at your output. 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 0 °C to 70 °C. It runs with a maximum temperature coefficient of 20ppm/°C(Typ).
