Texas InstrumentsTL1431QDReferencias de tensión

Even in the event of large power supply variations, this TL1431QD voltage reference power management device from Texas Instruments can produce and maintain a precise DC voltage. With a voltage no larger than 37 V, this will supply sufficient power to your circuit. It has an initial accuracy of 0.4%. With an output that has a voltage of 2.5 to 36 V, this is power management at its best. This voltage reference circuit supports shunt 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.
