The LM385BXM-1.2/NOPB\'s working principle is based on the Zener diode, which is the heart of all voltage references and many current sources. It is a p-n junction diode in which the magnitude of current to a given voltage is extremely constant. The LM385BXM-1.2/NOPB consists of a Zener diode and other support circuitry to provide improved performance and operation over a wide temperature range. The Zener diode is connected in series with an adjustable current source to stabilize the output voltage. The adjustable current source is used to control the Zener diode\'s law of Zener breakdown, which is the process of the diode\'s electrical properties changing with an increased voltage applied across it. With the addition of the adjustable current source, the LM385BXM-1.2/NOPB is able to provide a very stable output voltage over a wide operating temperature range.

The LM385BXM-1.2/NOPB also includes several other components to improve performance and accuracy. A temperature compensation circuit reduces the initial error and stress on the Zener diode. A voltage regulator maintains the current drawn by the voltage reference circuit at a constant level. An AC bypass capacitor reduces noise and ripple in the output circuit. Finally, additional filtering and compensation circuitry improves the LM385BXM-1.2/NOPB\'s accuracy and stability.

The LM385BXM-1.2/NOPB is a high precision, ultra-stable reference source, making it ideal for voltage references in a variety of applications. With a wide operating temperature range, low voltage drift, low noise, and tight initial accuracy, the LM385BXM-1.2/NOPB is one of the best performing, most reliable voltage references available. It is well-suited for precision applications in data acquisition systems, power supplies, and instrumentation that require a stable and consistent reference voltage. The LM385BXM-1.2/NOPB is truly an all-around excellent reference source.
