The LM431AIMX/NOPB is a member of the Power Management Integrated Circuit (PMIC) – Voltage Reference family of devices.

These fixed/adjustable voltage-reference devices are designed to provide a regulated reference voltage output of 1.225 V and have excellent temperature stability and tolerance. The devices feature a very low temperature coefficient (TC) of 0.2 mV/°C (max) and have a typical tolerance of ±0.5% at 25°C.

The LM431AIMX/NOPB is a low power, adjustable three-terminal voltage-reference diode. It is designed to provide a highly accurate, temperature-stable reference for use in many types of circuits. The LM431AIMX/NOPB also features high input impedance, a low output noise and excellent dynamic characteristics. Additionally, the device features precision trimming of its reference voltage output to compensate for any tolerance errors.

The most significant features of the LM431AIMX/NOPB are that it provides precise and multiple reference voltages, has excellent temperature stability, and has a wide operating temperature range of -20°C to +85°C.

When used as a voltage reference, the output voltage is determined by the amount of current applied between the ADJ terminal and the -VIN terminal. The reference voltage is determined by the ratio of the current applied to the ADJ terminal to the current flowing out of the same terminal. The ADJ terminal also requires a small current input to provide the desired reference voltage.

In addition to its use as a voltage reference, the LM431AIMX/NOPB can also be used in high-accuracy temperature-compensation applications by monitoring the voltage at the device’s Temperature Sense terminal. The device’s internal temperature sensing circuitry can detect changes in ambient temperature using only a single terminal for temperature sensing. This allows for high accuracy temperature regulation with minimal application design effort.

The LM431AIMX/NOPB has a wide range of applications in a variety of different industries. It can be used in automotive, aerospace, telecommunications, industrial, medical, and consumer applications. For example, the device can be used in industrial temperature controllers and communication equipment. It can also be used in battery management systems, mobile phones, and in the automotive industry for power supplies, engine or transmission control systems, and vehicle safety systems.

The LM431AIMX/NOPB is designed to be a low power, low noise, and highly accurate voltage reference diode. It provides precise and multiple reference voltages with excellent temperature stability, a wide operating temperature range, and highly accurate trimming of its reference voltage output. As a result, it is an ideal device for many different types of applications, including voltage regulation, temperature control, and battery management.
