TPS75325QPWPRQ1

TPS75325QPWPRQ1 is a linear voltage regulator. It belongs to the Simple Switcher family of PMICs (power management integrated circuits) offered by Texas Instruments. It is designed for providing ultra-low power solutions for powering portable devices such as wearables, smartphones, tablets, and laptop computers. It is a low quiescent current (DCR=0.5μA) and adjustable output voltage linear regulator that is available in an exposed P-dip (EPD) package which provides flexibility in budget and performance requirements.

Application Field

The TPS75325QPWPRQ1 is used in applications where high efficiency is necessary, such as power Brick applications, power over Ethernet (PoE) solutions, wearables, and ultra-low power systems. In addition, the TPS75325QPWPRQ1 is used for intelligent motor control applications where a programmable and adjustable output voltage is necessary. This device can be used to provide a supply voltage from 2V to 6V, with a current capability of up to 150mA. The output voltage can be adjusted via an external reference voltage applied to the REFIN pin.

Features

The TPS75325QPWPRQ1 is highly integrated and flexible, with features such as a wide input voltage range (2.5V to VOUT + 6V), low quiescent current (0.5μA), and a programmable output voltage that can be adjusted by an external reference voltage. The device also provides an adjustable current limit and thermal shutdown protection.

Working Principle

The TPS75325QPWPRQ1 works on a linear voltage regulating principle. A linear voltage regulator is a type of electronic regulator that maintains a constant output voltage by varying the input voltage. The linear regulator takes the input voltage and uses it to control the output voltage of the device. The output voltage is regulated by a series of transistors, resistors, and capacitors that control the amount of current allowed to flow through the regulator. The voltage output is compared to a reference voltage, and the transistors are used to adjust the amount of current that is allowed to pass through the regulator. This allows the linear regulator to maintain a steady output voltage, even when the input voltage changes.

Conclusion

The TPS75325QPWPRQ1 is a linear voltage regulator that offers ultra-low power solutions for powering portable devices. It offers a wide input voltage range, low quiescent current, adjustable current limit, and thermal protection. The output voltage can be adjusted with an external reference voltage applied to the REFIN pin. The device is used in applications where efficiency is necessary such as power Brick applications, PoE solutions, wearables, and ultra-low power systems.
