• Load transient response of less than 10 µS.
• Accurate output voltage overload and short circuit protection.
• High-precision output voltage accuracy of ±2.5%.
• Shutdown mode current of only 50 µA.

Application Field

The LM4132CMF-2.5/NOPB Voltage Reference can be found in a plethora of applications. These include, but are not limited to, industrial power supply systems, medical instrumentation systems, and test/measurement instruments. It is also useful for detecting and controlling power switchovers without negatively affecting the accuracy of the output.

Working Principle

The LM4132CMF-2.5/NOPB Voltage Reference works by first regulating the incoming power via the voltage reference. It uses an op-amp feedback loop to accurately sense and adjust the input voltage, as required by the application. Additionally, the integrated voltage regulator helps maintain a stable output voltage even when the load current changes. This helps to ensure reliable and consistent power delivery.

In addition to the voltage regulation, the LM4132CMF-2.5/NOPB Voltage Reference also provides robust protection against overload and short circuit conditions. This is accomplished by the integrated current sensing and over-voltage shutdown circuitry. When an overload or short circuit situation is detected, the output voltage will shut down until it can be safely re-enabled.

Overall, the LM4132CMF-2.5/NOPB Voltage Reference is an ideal solution for accurate and reliable power regulation. It offers exceptional accuracy and protection, as well as a wide input voltage range and a low shutdown current. This makes it well-suited for a variety of industrial and consumer applications.
