The LM431AI/NOPB is a programmable shunt regulator diode and a member of the PMIC-Voltage Reference family. It is a highly integrated, voltage-programmable device characterized by low total error, wide input and output voltage range, and wide temperature range. The LM431AI/NOPB combines the precision and low power consumption of a monolithic linear voltage reference with the flexibility and cost savings of a two-terminal shunt regulator. This voltage reference is manufactured using advanced CMOS processes, allowing the use of a wide variety of applications.

The LM431AI/NOPB has two operational modes: voltage mode and current mode. In voltage mode, the device is designed to regulate the output voltage to a user-defined level. This is achieved by adjusting the internal voltage reference for the desired voltage. In current mode, the LM431AI/NOPB is designed to regulate the output current to a user-defined level. This is done by adjusting the device\'s internal current source for the desired current level. Both modes are controlled by a user-programmable logic pin.

In either mode, the LM431AI/NOPB can be used to provide voltage regulation or current-limiting protection. The device has an adjustable output voltage range of 0.8V to 15V and a maximum output current of 2A. The device has an on-chip temperature-compensated precision reference, voltage sense input, and temperature compensation pin. This allows the device to maintain excellent stability and accuracy over temperature and environmental conditions.

The LM431AI/NOPB is available in a variety of packages, including a 2.54mm dual-in-line package, an 18-pin surface mount, and a single-in-line package. The device can also be ordered in a pre-calibrated model of 10 mV per degree Celsius temperature coefficient from −20°C to +85°C. This makes it easier to use the LM431AI/NOPB in applications that require excellent temperature stability.

The LM431AI/NOPB can be used in many different types of circuits, such as power supplies, automotive systems, communications systems, measurement equipment, audio devices, and motor control circuits. It can also be used for overvoltage and overcurrent protection, clock circuitry, temperature sensing, logic level translators, and several other applications where precision is required.

Overall, the LM431AI/NOPB is an excellent diode voltage reference that offers flexibility and stability in a variety of applications. It is a highly integrated device with a low total error that provides excellent performance and reliability over a wide temperature range. With its wide input and output voltage range, the LM431AI/NOPB is an ideal choice for precision voltage regulation and current limiting protection, and can be used in a variety of applications to meet the most demanding requirements.
