Working Principle

The AP7115-25WG-7 is a linear voltage regulator that uses a common feedback mechanism to regulate its output voltage. This linear regulator uses a feedback input and a control loop to compare the input voltage and the reference voltage of the output voltage. The regulator will then adjust the output voltage by adjusting the operating current. This operating current is determined by the amount of resistance the amplifier presents in the feedback loop. When the input voltage is higher than the output voltage, the amplifier is in active region and starts to sink current out of the source terminal to the output of the regulator.

This operating current generates a voltage at the resistor which is amplified by the error amplifier and compared to the reference voltage. The error amplifier then generates a difference signal to the power transistor and will increase or decrease the current through the resistor to reach the desired output voltage. The current is then passed through the inductor, output capacitor and other components of the regulator to provide a steady output voltage. The regulator also includes additional features such as thermal protection and over current protection.

Conclusion

The AP7115-25WG-7 is a high performance linear voltage regulator from Diodes Incorporated, and is suitable for a range of applications such as solar power, charging and other high efficiency power supply applications. It features low drop-out performance and a wide input voltage range that makes it suitable for applications with tight regulation requirements. The regulator is capable of working at peak full load of 25A, due to its excellent transient response and integrated linear voltage regulator.
