TPS72725DSET Application Field and Working Principle

TPS72725DSET is a low-voltage, low-cost linear regulator from Texas Instruments. It is designed as a basic and convenient solution for applications needing low quiescent current and low devices power in a very small package.

Since its release, the TPS72725DSET has become one of the most popular linear devices in the market and it is used in applications where low cost and low power dissipation is needed. Its features make it perfect for implementing adjustable power supplies, main power distribution and standby power supplies.

Application Fields

The TPS72725DSET is suitable for a variety of applications. It provides low-voltage output of up to 8V and 25mA to applications needing output current up to 25mA. It can also be easily integrated with other power supplies in a basic linear regulator configuration. It is used in automotive applications such as Powertrain, Infotainment, Body, and Accessory systems, and it can also be used for industrial applications.

Some examples of common applications are:

• GPS systems
• Communication systems
• Medical devices
• Aircraft data collection systems
• Automotive instrumentation systems

Working Principle

The TPS72725DSET works through a relatively simple arrangement of two transistors driven by a controlling voltage of 5V or less. The output voltage can be adjusted by changing the control voltage. The two transistors act as a variable resistor, and the output voltage is regulated by varying the voltage drop across the two transistors.

The TPS72725DSET is capable of delivering a wide output range starting from 0.85V up to 8V and it will maintain a constant output voltage even when the input voltage is varying. Furthermore, the output voltage is adjustable simply by changing the applied control voltage for fine tuning the output. The current limiting feature of the device further makes it perfectly suitable for industrial and automotive applications.

Conclusion

The TPS72725DSET is developed to meet the needs of low-cost and low-power applications. Its features make it one of the most popular linear devices in the market with wide application fields such as automotive and industrial. Its simple arrangement and variable regulation make it perfect for designing adjustable power supplies, main power distribution and standby power supplies.
