The TPS72715YFFR is a low-dropout (LDO) linear voltage regulator integrated circuit (IC) designed for use in applications requiring higher accuracy voltage regulation. This article covers the application fields and the working principle of the TPS72715YFFR.

The TPS72715YFFR is part of the voltage regulator linear category of Texas Instruments\' Power Management IC (PMIC) product line. It features a very low dropout voltage of 187mV at 100mA, high accuracy, and fast transient response, making it an ideal IC for voltage regulation designs requiring high precision. The TPS72715YFFR is capable of delivering up to 500mA of continuous output current and is offered in a small 2x2x0.8mm 10-pin uDFN package.

The TPS72715YFFR operates from input voltages ranging from 2.2V to 6V and provides very precise output voltages from 0.8V to 5V. It is also designed for ultra-low quiescent current, enabling it to be used in battery-powered applications. The device also has an integrated reverse current protection mechanism and a power-disconnect circuitry to ensure safe operation in the event of an input voltage surge, making it suitable for use in a wide range of applications.

Working Principle of TPS72715YFFR

The TPS72715YFFR is designed around a basic linear regulator IC. A linear regulator regulates a voltage by using a power transistor or pass transistor, normally a bipolar-junction transistor (BJT) or a field-effect transistor (FET), to enable or disable current flow through the circuitry. In effect, the regulator works by converting the difference between the input voltage V_IN and the feedback voltage V_FB into a variable resistance that controls the amount of current passing through the device. The output voltage is maintained at the set point by controlling the amount of current passing through the device.

The TPS72715YFFR compares the voltage feedback from the output with a reference voltage. When the output voltage is lower than the reference, the TPS72715YFFR increases the current flow to the load until the output voltage is equal to the reference. Similarly, when the output voltage is higher than the reference, the TPS72715YFFR decreases the current flow to the load until the output voltage is equal to the reference.

The TPS72715YFFR includes several features intended to improve power efficiency, reduce electromagnetic interference (EMI), and protect the device from damage due to over-temperature or excessive current. These features include an adjustable current limit, an adjustable current-limit threshold, an adjustable soft-start (SS) time, an adjustable startup delay, an adjustable power-good delay, and over-temperature protection.

Conclusion

The TPS72715YFFR is a low-dropout (LDO) linear voltage regulator designed for very precise voltage regulation in a wide range of applications. Its high accuracy and fast transient response characteristics, combined with its low dropout voltage and integrated protection mechanisms, make it an ideal IC for demanding applications requiring precise and safe voltage regulation.
