• Application field

The SPX1587T-L-5-0/TR is designed as an advanced, low-cost and low-noise linear voltage regulator. It is ideal for use in power management and signal processing systems, including timer circuits, frequency conversion, and signal processers, as well as RF power amplifiers. It is also suitable for high-power industrial and medical applications.

• Working Principle

The SPX1587T-L-5-0/TR operates with a built-in controller and a wide band gap P-channel MOSFET device. The built-in controller adjusts the voltage output, while the P-channel MOSFET provides efficient power conversion. The linearity of the voltage regulator is based on the P-channel MOSFET acting as a transistor to amplify the current from the output end and the input end. The current from the output end is sent to the regulator, which then determines the voltage level of the output. The input current is then sent to the voltage regulator and the output current is determined by the difference between the input voltage and the output voltage.

The SPX1587T-L-5-0/TR\'s integrated protection features include overcurrent protection, over voltage protection, and over temperature protection. The overcurrent protection is triggered when the input current is higher than the maximum supported current level. The overvoltage protection is triggered when the output voltage is higher than the maximum output voltage. Finally, the over temperature protection is triggered when the device temperature exceeds the maximum operable temperature.

• Conclusion

The SPX1587T-L-5-0/TR is an excellent choice for a low-noise, low-cost and certified linear voltage regulator. Its features enable it to provide reliable performance in power management and signal processing applications, as well as many other high-power industrial and medical applications. The integrated protection features make sure that the device is protected against overvoltage, overcurrent and overheating conditions, making it an ideal choice for a variety of applications.
