The LMV431ACM5/NOPB is a Voltage Reference IC belonging to the family of Power Management ICs (PMIC) used to convert the input voltage into a precisely regulated output voltage through voltage reference technologies. It is used to provide a stable, adjustable regulated output voltage of 2.5V, 3.3V and 5V and offer enhanced noise, line and load transient performance as well as lower output voltage noise and power consumption. This device provides a constant output voltage with temperature and voltage line transients, or load changes.The pin configuration of LMV431ACM5/NOPB includes three stable voltage output pins (VIN, VOUT and VCC), an enable pin for power supply control and an adjustment pin for driving the reference voltage. Moreover, it is an adjustable three-terminal integrating regulator IC featuring fast transient response and low noise. This voltage regulator IC is available in an SOT-23-5L, SC70-5 and TSOT-6 package.

The working principle of LMV431ACM5/NOPB is based on the fact that it uses a band-gap voltage reference for providing the desired voltage output. This voltage reference relies on the principle of creating a reference voltage that lies between the two valley points of the semiconductor’s diode voltage-temperature characteristics curve i.e., the magnitude of the output voltage remains constant with change in temperature. Voltage references are widely used in various applications such as analog to digital converters, switch mode power supplies, voltage regulation, LED applications, switching regulators and processor or logic circuits.
