It is also widely used in household electronics such as DVD players, CD players, DVD recorders, DVD players and TVs.

Working Principle

The AP1084K15G-13 regulator is based on a linear regulator topology. The output voltage is set by an external voltage divider, with a reference voltage of 1.3V. The voltage on the output pin is compared to the reference voltage by the error amplifier, and if there is a difference, a correction factor is applied by the internal error amplifier to the MOSFET gate output to maintain a constant output voltage. This operation is continuous and causes no glitches.

In addition, this voltage regulator is designed to require only a minimal number of external components, allowing the user to save space on the PCB and the cost of components. It also features a low power dissipation and a low quiescent current, and it is also capable of delivering up to 500 mA of output current.

Conclusion

The AP1084K15G-13 is a highly efficient and versatile linear voltage regulator. It offers wide input and output voltage ranges, high power load capacity, and high temperature stability. It is an ideal low-noise and high PSRR performance solution for many applications, including industrial, communications, and household electronics.
