The LM4041BIX3-1.2+T is a precision two-terminal adjustable voltage reference device, which is featured as an integrated circuit from the PMIC (Power Management IC) voltage reference family. The device provides a precise external adjustable reference voltage, used in aerospace applications, automotive subsystems, and other high-precision industrial and consumer applications. It is capable of providing an output voltage that is adjustable from 0.8V to 1.2V by connecting a resistor divider network to the adjusting pin.

The LM4041BIX3-1.2+T makes use of a well-established topology that is commonly used in voltage references. This device consists of a high-stability bandgap reference, a series pass element and an output amplifier, together providing a precise voltage reference. The bandgap reference provides a reference voltage of 1.2V, which is determined by the incremental voltage created by the current in a constant current source passing through a thin-film resistor network. The series pass element, on the other hand, is a current sink capable of controlling the output voltage. Lastly, the output amplifier compensates any unwanted output voltage swings due to load transients.

The LM4041BIX3-1.2+T IC is designed to operate over a wide range of temperature, from -55°C to +125°C. It ensures a low output temperature coefficient, which is offset while maintaining a high level of accuracy. The device also provides a wide input voltage range, allowing it to work with most automotive power supplies, as well as other systems needing higher-voltage input levels. In addition, the device offers various features for robust protection, including protection against electrostatic discharge (ESD), thermal shutdown, and ripple rejection. It also delivers low noise output, which makes it suitable for noise-sensitive applications.

The LM4041BIX3-1.2+T is ideal for applications that need an adjustable voltage reference for precise, stable, and accurate output voltages. It is widely used in automotive, military, commercial, industrial and medical applications, such as motor control, power management systems, power supplies, DC-DC converters, and automotive subsystems. It can also be used in other high reliability applications, such as spacecraft, aircraft and instrumentation, as well as radar, communication, and automotive system components.

In summary, the LM4041BIX3-1.2+T is an adjustable voltage reference IC from the PMIC family offering precise, stable, and accurate output voltages. The device is widely used in automotive, military, commercial, industrial, and medical systems, and is suitable for noise-sensitive applications. It is designed to operate over a wide range of temperatures, and offers robust protection features, such as ESD and thermal shutdown. The device also provides a low-temperature coefficient and wide input voltage range, making it ideal for applications that requires a precise and accurate adjustable voltage reference.
