Working Principle of AP7167-FNG-7

The AP7167-FNG-7 operates as a linear regulator. The input voltage is applied to the device through a load and the device reduces the output voltage to the desired voltage level. The output voltage is controlled by a low current control pin, which is used to adjust the output voltage. The reference voltage of the device is controlled by an external voltage reference. The current is kept at a low constant level in order to maintain low power dissipation. The device is then allowed to compensate for changes in the output voltage due to line and load regulation. The device is enabled by an enable pin and can be disabled when the enable pin is set to low.

Conclusion

The AP7167-FNG-7 is a linear regulator from Anpec Electronics Corporation. The device offers a low drop-out voltage, high accuracy, fast transient response, and low drop-out current in a low-power shell. It is ideal for applications requiring precise voltage regulation and can be used in battery-operated systems, portable devices, automotive electronics, industrial automation systems, power management of electronic devices, and data logging systems. The device operates as a linear regulator with the output voltage controlled by a low current control pin and the reference voltage controlled by an external voltage reference.
