The LMV431IM5X/NOPB is a three-terminal adjustable shunt regulator developed by Texas Instruments that is categorised as a PMIC (Power Management IC) voltage reference device. It is a low power, high accuracy device suited for use in portable and general purpose applications such as D/A converters, DAC controllers, thermocouple amplifiers, power supplies, test instruments and data acquisition systems.When it comes to applications and working principles, the LMV431IM5X/NOPB is an ideal device for designing adjustable current or voltage sources because it is able to maintain precise output levels over a wide temperature range. The device features a maximum output voltage of 3.2V and a minimum output voltage of 0.5V, thus providing flexibility and making it suitable for various purposes. It has a maximum temperature coefficient of 30 ppms/°C and a maximum initial accuracy of 5 mV. The peak-to-peak output noise is also very low, at a maximum of 17 μg √Hz.The LMV431IM5X/NOPB also has a wide input voltage range of 3.0V to 15V, allowing it to be used in most designs without the risk of damage or instability. Additionally, the device\'s low quiescent current of only 1.5 μA and low dynamic output impedance of 5 Ω make it ideal for a wide range of power supply applications.When it comes to design considerations, the LMV431IM5X/NOPB features an open-loop voltage gain of 130V/V, which helps to maintain precise output levels. Furthermore, it has an adjustable temperature coefficient that allows for compensation of any output drift. Another useful feature is its active current limit, which protects against overloads or inrush. Lastly, the device is protected against electrostatic discharge (ESD) up to ±8 KV, further ensuring its reliability and durability.Overall, the LMV431IM5X/NOPB is an excellent choice fordesigning adjustable current or voltage sources, power supplies, and other applications requiring a precise and reliable output. Its features make it well-suited for portable, general-purpose, and even specialized applications.
