The LM4128AMF-2.5 Voltage Reference is an integrated circuit produced by Texas Instruments. It is a gyroscopic voltage regulator that provides accurate, noise resilient, and low-noise voltage reference and is specific to isolated power supply applications. This integrated circuit is ideal for point-of-load regulation, as it can deliver up to 2.5A of output current, making it suitable for moderately high-current applications. The reference voltage can be adjusted in increments over a desired range, and is accurate to within plus or minus 0.5% of the desired voltage. The LM4128AMF-2.5 can provide a steady voltage in temperatures ranging from 0 to 125C.The LM4128AMF-2.5 is designed to provide consistent voltage regulation during varying temperatures. As the temperature of the device rises, the compensated output voltage automatically adjusts to maintain the desired reference voltage. For extreme temperatures, the device outputs a temperature-dependent feedback voltage, responding quickly to changes in temperature. This keeps the voltage source steady even in temperatures that most other references are unable to handle.The LM4128AMF-2.5 Voltage Reference also features a low dropout of .2V at 1A and .1V at .25mA. This means that the reference voltage stays the same even when the load varies from 5mA to 2.5A. This makes the device ideal for low noise, high accuracy regulation applications.The LM4128AMF-2.5 can also be used in applications where there is a need for a low voltage switch. The output voltage can be set as low as 0.89V and up to 3V, and can be adjusted continuously in 0.1V increments. This makes it ideal for applications where the load needs to be switched off momentarily to prevent overvoltage.In the formation of noise tolerant power supplies, the LM4128AMF-2.5 can be used to help reduce fluctuations between ground and other parts of the circuit. This helps to reduce the amount of noise that would otherwise be propagated by the circuit elements and eliminates the need for bulky filtering components. This helps improve the reliability of the power supply and improves its noise immunity.In summary, the LM4128AMF-2.5 Voltage Reference provides a powerful and reliable integrated reference source for isolated power supply applications. It provides accurate, low-noise voltage reference for up to 2.5A of output current and incorporates temperature compensation to maintain a correct voltage even in extreme temperatures. Its low-dropout supply and switchable output makes it well suited for low noise, high accuracy regulation applications and its noise tolerant power supply reduces the amount of noise propagated by the circuit elements. The LM4128AMF-2.5 is a versatile and highly accurate voltage reference and is ideal for a variety of applications.
