TPS73201DCQRG4 Application Field and Working Principle

The TPS73201DCQRG4 is a linear voltage regulator with PMIC or Power Management IC integrated circuit. It\'s manufactured by Texas Instruments and used to convert the supplied variable input voltage into a constant output voltage. The TPS73201DCQRG4 is designed with a low-power, low-dropout regulator that supports up to an output current of 300mA and an input voltage of up to 12.5V.This IC combines current regulation and temperature protection with an integrated bridge rectifier, minimizing the need for external components. The TPS73201DCQRG4\'s built-in power-saving mode helps manage system power draw when under limited power-supply conditions, providing additional system level protection.

Applications

The TPS73201DCQRG4 is suitable for a wide-range of applications, such as in compute, communications and storage systems, USB, motor control, and point of load applications. In particular, this IC is often used in mobile and battery-powered devices, and in industrial and automotive applications that require precise regulation and low power consumption.

Features

The TPS73201DCQRG4 features dual power good outputs with power even under light load conditions, an internal temperature protection to regulate output voltage, a diagnostic feedback for short circuit protection, and an advanced power saving mode. This IC has a low dropout voltage of 160mV, an over-temperature protection of 100C, and can provide up to 300mA of output current. It also has a 0.2%/V line regulation and a 0.2%/V load regulation.

Working Principle

The TPS73201DCQRG4 is a linear regulator that works by using a PMOS or P-Channel MOSFET transistor to regulate the output voltage. The transistors\' gate voltage is determined by the output voltage and its gate input current, which is regulated by the internal circuitry of the IC.When the input voltage is greater than the output voltage, the current regulator draws the needed current from the PMOS transistor, maintaining the desired output voltage. The output current is then limited to a maximum of 300mA, and the IC will enter into a power-saving mode when under low power-supply conditions.

Conclusion

The TPS73201DCQRG4 is a linear voltage regulator that provides a precise and low-power solution for a wide-range of industrial and automotive applications. This IC is well suited for mobile, battery-powered devices and other applications requiring precise regulation and low current draw. By using a PMOS transistor, the TPS73201DCQRG4 is able to regulate the output voltage and current, controlling the output voltage within a specified range. It also features an advanced power-saving mode, making it an ideal choice for power management.
