AP7313-25SAG-7 Application Field and Working Principle

The AP7313-25SAG-7 is an adjustable, low-dropout voltage regulator manufactured by Anpec Electronics Corporation, a global leader in the manufacture of high quality integrated power management circuits. It belongs to the PMIC (Power Management IC) family of voltage regulators, with the Linear classification. By combining low-dropout results and exceptionally adjustable output voltage from 0.8V to 2.6V, this regulator offers users a highly efficient and reliable power solution.

Application Field

The AP7313-25SAG-7 is designed to be used in various kinds of electronics, such as consumer networks, consumer medical devices, smart meters, telecom systems and industrial control systems. Its adjustable, low-dropout voltage feature provides users with the ability to lower the power dissipation, meaning less energy is wasted, thereby promoting energy efficiency.

Working Principle

The regulator works by lowering input voltage and maintaining output voltage at a constant level. It changes the output voltage level by allowing a controlled amount of current to pass through the resistor divider, which is connected to the output of the regulator (FB pin). The output voltage is then kept constant with reference to the FB pin for varying loads and input voltages. This is done using a Variable Operational Transconductance Amplifier (VOTA) in a feedback loop from the output of the regulator to an internal regulation block.

The internal regulation block consists of an error amplifier, a series bandgap reference, an internal compensation network and the VOTA. This block using the VOTA generates a current proportional to the difference between the output and the reference voltage. Once the current is generated, it is connected to the error amplifier and compared to a reference current generated by a resistance divider. The error amplifier then adjusts the output voltage at the FB pin, and the regulation loop is again closed.

Moreover, the AP7313-25SAG-7 also comes with programmable current limit, over-temperature limit and over-voltage shutoff features, making it highly reliable in circuit operations.

Conclusion

In short, the AP7313-25SAG-7 is an adjustable, low-dropout voltage regulator that provides highly efficient and reliable power management solutions for a range of electronic components, from consumer networks to smart meters. With its integrated Variable Operational Transconductance Amplifier, it maintains output voltage at a constant level by allowing a controlled amount of current to pass from the feedback pin. The AP7313-25SAG-7 also comes with additional safety features that protect against over-temperature, over-voltage and excessive current.
