LM4120AIM5X-2.5/NOPB Integrated Circuits (ICs)

LM4120AIM5X-2.5/NOPB is a PMIC (Power Management Integrated Circuit) used as a voltage reference. Its main purpose is to references, improve transient response and reduce output voltage overshoots. This device is built on the same process technology, and has common packaging, making it easy to replace any similar reference device. It is suitable for high-speed applications and low-voltage applications due to its low offset voltage and low input power.

Application Field

The LM4120AIM5X-2.5/NOPB voltage reference can be used to regulate the output voltage in a wide variety of applications. These include power supplies, battery chargers, distributed power systems, data converters, high-speed motor drives, portable equipment, high-efficiency displays, and a variety of other industries. In addition, it can be used as a reference in analog-to-digital (A/D) or digital-to-analog (D/A) converters.

Work Principle

The LM4120AIM5X-2.5/NOPB is based on the reliable band gap reference topology. It consists of two reference transistors operating in series connection and connected to the two external resistors. The collector of both transistors is connected to the output terminal and the values of the external resistors govern the output voltage. By setting the value of these resistors appropriately, one can regulate the output voltage to the desired level.

The LM4120AIM5X-2.5/NOPB is also equipped with an input pin for controlling the output voltage. This pin is used for programming the reference voltage. The internal circuitry of this device is designed to control the output voltage when the input pin is driven by a low voltage, such as a voltage divider. This allows the output voltage to be adjusted precisely regardless of the voltage of the load connected to it.

The LM4120AIM5X-2.5/NOPB also has excellent temperature performance, with a very low temperature coefficient of less than 0.01%. This means that it is stable over a wide temperature range, making it suitable for a variety of applications.

The LM4120AIM5X-2.5/NOPB voltage reference is also available in a range of output voltage levels, from 0V to 4V. This makes it suitable for both low-voltage and high-voltage applications.

Overall, the LM4120AIM5X-2.5/NOPB is a reliable and accurate voltage reference, ideal for a wide range of applications. It is easy to use, offers excellent performance, and costs relatively little for such a powerful device.
