TPS7201QPWG4 application field and working principle

The TPS7201QPWG4 is a low-noise, ultra-low-dropout linear voltage regulator featuring an output voltage accuracy of 0.83%. It is an ideal choice for providing power in a wide range of processor, battery-powered, and portable applications. This article will introduce the application field and working principle of TPS7201QPWG4.

Application field

TPS7201QPWG4 is suitable for use in processors, battery-powered systems, and portable applications. It is capable of delivering up to 125 mA of output current at up to 2.4V, with a very low dropout voltage of only 125mV at full load. It features excellent load and line transient responses and very low output noise, making it ideal for applications where high accuracy, low noise, and stable output voltage are important.

TPS7201QPWG4 is particularly suitable for low-power applications as it has a wide input voltage range (1.3V to 8V) and a low quiescent current of only 10μA. It has a wide operating temperature range, allowing it to be used in commercial, industrial, and automotive applications. It also has logic controlled enable/disable pins to enable or disable the regulator without affecting the system supply. Additionally, it offers protection against-over-current, over-temperature, and reverse current.

Working principle ...

TPS7201QPWG4 is a low dropout linear voltage regulator. The working principle of the voltage regulator involves two stages. First, when the device receives an input voltage it converts the initial voltage into an amplified output using field effect transistors (FETs). This output is then filtered and regulated by an internal voltage regulator. The internal voltage regulator monitors the output voltage, and ensures that it remains constant, regardless of input voltage or load variation. When input voltage is greater than the output voltage, the FETs will regulate the output by transferring power from the input to the output.

The output of the regulator is stable and accurate. It has an output voltage accuracy of 0.83%, and a wide temperature range of -40°C to +85°C for commercial applications and -40°C to +105°C for industrial and automotive applications. It also features low output noise, low quiescent current, fast load transient responses, and over-current and over-temperature protection.

Conclusion

TPS7201QPWG4 is an ultra-low-dropout linear voltage regulator which can provide up to 125mA at up to 2.4V. It has a wide input voltage range, a low quiescent current, excellent load and line transient response, and low output noise, which makes it ideal for applications where high accuracy, low noise, and stable output voltage are important. Additionally, it offers protection against over-current, over-temperature, and reverse current.
