PMIC - Voltage Reference

Power Management Integrated Circuits (PMICs) are a class of integrated circuits that primarily produce and manage power for various electronic components. One important subset of PMICs are voltage references, which are used to ensure that a given voltage stays at a given level. Voltage references are particularly critical in circuit designs, and LM336Z-2.5/NOPB is a widely used voltage reference within the industry. This article discusses the application field and working principle of LM336Z-2.5/NOPB.

Application Field of LM336Z-2.5/NOPB

The LM336Z-2.5/NOPB is a two-terminal precision adjustable shunt voltage reference. It is designed to provide a stable and precise voltage reference level. Its adjustable circuit allows users to easily adjust the output voltage to a desired value between two and five volts. Common applications of LM336Z-2.5/NOPB include power management for hard drives, digital and mixed signal circuits, voltage reference for pressure sensors, and system reference in industrial systems, among many others.

Working Principle of LM336Z-2.5/NOPB

At the core of the LM336Z-2.5/NOPB is an inherently stable, adjustable voltage reference. This is made up of two terminals—the reference pin and the adjustment pin. The reference pin is connected to a source of regulated, adjustable voltages. The adjustment pin is the actual output of the voltage reference and is connected to the voltage-setting circuitry.To adjust the output of the LM336Z-2.5/NOPB, the user adjusts the voltage at the adjustment pin until it is equal to the reference voltage. This causes the output voltage to remain constant, regardless of the load or operating temperature.The LM336Z-2.5/NOPB additionally includes an internal band-gap reference diode to improve overall device performance. This diode ensures that the output voltage of the device remains constant, even when the supply voltage changes.

Limitations of LM336Z-2.5/NOPB

Although the LM336Z-2.5/NOPB is easy to use and offers many advantages, there are some limitations to its use. First, the LM336Z-2.5/NOPB is not suitable for high-temperature applications, as it is prone to temperature drift. Second, the LM336Z-2.5/NOPB is limited in its output range, as it only provides a constant voltage between two and five volts. Finally, the LM336Z-2.5/NOPB is not well-suited for high-current applications, as it can only handle up to 600 mA.

Conclusion

The LM336Z-2.5/NOPB is a widely used two-terminal adjustable voltage reference. It is well-suited for applications where a stable and reliable voltage is needed. Its adjustable circuit allows users to easily adjust the output voltage to a desired value between two and five volts. Additionally, the LM336Z-2.5/NOPB includes an internal band-gap reference diode to improve overall device performance. There are, however, some limitations to the use of the LM336Z-2.5/NOPB, such as its inability to handle high-temperature, high-current applications.
