TPS76801QPWP Application Field and Working Principle

The Texas Instruments TPS76801QPWP is a low-power, low-dropout linear voltage regulator featuring an integrated system Power Management IC. The device is used to provide single-cell output regulation in a wide range of mobile and consumer applications. It has a maximum output current of 250 mA and a maximum output voltage of 1.8 V. In addition, the device is designed to reduce the need for external components, therefore making it a valuable choice for low-power applications.

Application Field

The TPS76801QPWP is a low-dropout linear voltage regulator IC that can be used in various consumer and mobile applications. These include portable consumer electronics such as tablets, phones, portable media players and digital cameras. Features such as low quiescent power consumption and extended battery life make it well suited to be used in these types of circuits. It can also be used in larger electronic systems including data processing systems and automotive equipment. In addition, the device is well suited to be used for medical and industrial applications.

Working Principle

The device is based on a P-channel MOSFET transistor, which acts as the main switch in the regulator circuit. When the input voltage is higher than the output voltage, the P-channel transistor is activated, allowing current to flow from the input to the output. In this way, the output voltage remains at a steady level. To avoid overloading the device, the TPS76801QPWP also includes a power-down switch that shuts off the current when the output voltage reaches its limit. In addition, it also includes a reverse current protection circuit, which prevents current from flowing back into the device when the input voltage is too low or the output voltage is too high.

The device has a wide input voltage range, from 3.2 V to 18 V, which makes it suitable for use in applications where the input voltage may vary significantly. It also provides an efficient, low-dropout voltage regulation with a maximum of 1.5 V at full current, making it ideal for low-power applications. Furthermore, the device’s low quiescent current makes it well suited for battery operated systems, and its high PSRR enables it to resist noise from power supply sources such as AC adapters.

Due to its wide range of features and its ability to provide efficient and reliable power regulation, the TPS76801QPWP is an ideal choice for a variety of applications, especially for powering portable consumer electronics. Its robust design and low-power requirements make it a great choice for applications where a reliable, efficient and cost-effective solution is needed.
