In office automation, RV4145AN is often applied in calculating machines, personal computers and digital copiers, etc. In automotive electronic applications, RV4145AN can be used in engine control, car air conditioner control, etc.

Working Principle

RV4145AN is a low drop-out linear regulator, which is characterized by high integration, low quiescent current, low noise and fast switching speed. When the voltage of input power source is higher than the output supply voltage, the linear regulator can reduce the difference between the two voltages by the principle of conversion. The RV4145AN\'s output voltage can be determined by a built-in voltage reference, and its output current can be determined by the external resistor R1. In order to ensure the stable working state of the circuit, thermal protection, reverse polarity protection and short circuit protection are also provided by RV4145AN. Thermal protection can prevent the over-temperature occurrence, ensuring the normal operation of the circuit. Reverse polarity protection ensures that in the event of reverse connection, the original function of the circuit is not damaged, and the circuit can still work steadtly. Short circuit protection can effectively protect the external load, because it can automatically connect the external load when the load is short-circuited.

Conclusion

In conclusion, RV4145AN is a specialized component in the field of power management. It is characterized by high integration, fast switching speed and low power dissipation. RV4145AN is applied in multiple fields such as consumer electronics, mobile communication, medical devices, office automation, and automotive electronic. In addition, RV4145AN is also equipped with thermal protection, reverse polarity protection and short circuit protection.
