LM7805MP/NOPB is a voltage regulator Linear from the PMIC (Power Management Integrated Circuit) family. It is commonly used for the purpose of providing a steady output, regulating a power supply. This article will explain the application fields for the LM7805MP/NOPB and the working principles behind it.

Application fields for LM7805MP/NOPB

The LM7805MP/NOPB is often used by hobbyists and electronic engineers in several fields. It is usually used for supplying a steady voltage to a load, rectifying a complex AC power system, protecting an integrated circuit, or generally influencing the current flowing through circuits and components. It is mostly utilized in the designs of audio amplifiers and graphic cards, as well as power supplies.

Working principles of LM7805MP/NOPB

The LM7805MP/NOPB is built as an integrated circuit with a pass transistor, two bipolar transistors, and two precision resistors. It works on the principle of negative feedback, introducing a small error voltage between the output and a reference voltage. This causes the output to have a steady level, within a +/-10% tolerance. Contributing to the stability is a capacitor connected to the output that prevents large changes in voltage level in the event of sudden load variations.

The LM7805MP/NOPB is designed to supply an output of 5V with an input up to 18V. Its regulation capability is at least 1%. Digital Ground Imaging (DGI) technology has been incorporated in the scheme to make the power supply more efficient. The DGI provides better thermal dissipation, allowing the regulator to reach optimal performance.

The LM7805MP/NOPB also provides protection against short-circuit conditions and overheating. When it detects an abnormal current flow in the output, it automatically disconnects the load and shuts down the supply line. This helps to prevent any damage to the components or the board.

Conclusion

The LM7805MP/NOPB is a useful integrated circuit for hobbyists and engineers who need a steady output voltage in power supplies, amplifiers, and graphics cards designs. Its working principle involves negative feedback that stabilizes the output, with a +/-10% tolerance. Additionally, it also provides short-circuit and overheating protection to ensure the safety of the components.
