The TPS717285DCKT is popularly used in battery-powered portable devices, where its low quiescent current helps maximize battery life.

Application Field

The TPS717285DCKT is commonly used as a low-dropout linear regulator for portable devices, including tablets, smartphones, digital cameras, portable media players, and others. It can also be used in energy harvesting systems, such as solar and wind power systems, where its low quiescent current helps maximize battery life.

Working Principle

The TPS717285DCKT operates using a two-stage regulator topology that consists of a PMOS pass FET and an error amplifier. The PMOS pass FET is used to provide a low-dropout output and the error amplifier is used to adjust the output voltage. The output voltage of the regulator is set by connecting an external resistor divider on the adapters feedback inputs. The PMOS FET passes current when the voltage at the input exceeds the internal reference voltage, which is generated internally and set by an external resistor divider. The error amplifier keeps the output voltage of the regulator close to the reference voltage, thus providing a stable output voltage.

The TPS717285DCKT also includes many other features that enable it to operate in harsh environments. It has over-temperature protection, over-voltage protection, under-voltage protection, and short-circuit protection. It also features low noise operation and high efficiency. Furthermore, the TPS717285DCKT is AEC-Q100 Grade 2 certified, which ensures its high-quality operation for automotive applications.

Conclusion

The TPS717285DCKT Linear Voltage Regulator is an excellent choice for portable devices, energy harvesting systems, and even automotive applications, due to its low quiescent current consumption and low-dropout voltage. It features a two-stage regulator topology that is designed for stable operation under various environmental conditions and its high-quality components are AEC-Q100 Grade 2 certified. Overall, the TPS717285DCKT is an excellent choice for many power regulation applications.
