Even in the event of large power supply variations, this LM236AH-5.0/NOPB voltage reference power management device from Texas Instruments can produce and maintain a precise DC voltage. It has an initial accuracy of 1%. With an output that has a voltage of 5 V, this is power management at its best. This voltage reference circuit supports shunt topology. By operating at a load regulation of 12mV you can provide a constant voltage at your output. This voltage reference circuit has an operating temperature range of -55 °C to 125 °C.
