Introduction

The SPX1582T5-L is a low dropout (LDO) linear voltage regulator from Sonomax Technologies that is primarily used for powering bus systems, processors and other electronic circuits. It is a high performance, low noise, and highly integrated device providing an ideal method for controlling the DC output voltage and minimizing power dissipation in the system. This article will discuss the application field of the SPX1582T5-L and its working principle.

Application Field

The SPX1582T5-L is a high performance, linear voltage regulator designed for use in industrial, medical and networking applications. It is an ideal choice for bus systems, processors and other electronic circuits requiring low noise and less power dissipation. The device is highly capable of handling high switching currents up to 4A, allowing it to be used in a wide variety of applications. It is also capable of operating in extreme temperatures ranging from -40° C to +125° C, making it a great choice for harsh environments. Additionally, the device is designed to meet the ESD standards: IEC 61000-4-2, Level 2.The SPX1582T5-L is capable of providing regulated output voltages of 5, 6, 7.5, 8.5, 10, and 11.5V. The output voltage is set by a single external resistor, making it very easy to adjust. The device has a typical line regulation of 0.07 %/V, load regulation of 0.1 %/A, and quiescent current of 10uA at no-load. Furthermore, the device has built-in protection features such as thermal shutdown and overvoltage protection.

Working Principle

The SPX1582T5-L is a high performance, low noise, and highly integrated device providing an ideal method for controlling the DC output voltage and minimizing power dissipation in the system. The device features a voltage reference, an error amplifier, a current limiter, a power supply PWM controller, a low-noise oscillator, and an output switch.At the heart of the device is a high precision voltage reference, which is used to compare to the output voltage and provide a reference voltage for the error amplifier. The error amplifier then amplifies the difference between the output voltage and the reference and produces a signal which is then sent to the power supply PWM controller. The power supply PWM controller then sends a signal to the gate of the output switch, which regulates the current flow to the output and ensures the output voltage remains stable and accurate.The current limiter ensures that the current remains within safe levels. It monitors the current flowing to the output and limits it by limiting the current flowing through the output switch. The oscillator produces low-noise pulses which are used to synchronize the energy cycles between the output switch, allowing it to operate at higher efficiency.Finally, the device has built-in protection features such as thermal shutdown and overvoltage protection. Thermal shutdown occurs when the device reaches a certain temperature and turns off the electrical current to protect itself from damage. Overvoltage protection shuts off the output switch if the output voltage exceeds a certain level.

Conclusion

The SPX1582T5-L is a low dropout (LDO) linear voltage regulator from Sonomax Technologies that is primarily used for powering bus systems, processors and other electronic circuits. It features high performance, low noise operation, and is highly integrated with built-in protection features. The device is capable of operating in extreme temperatures ranging from -40° C to +125° C and is capable of handling high switching currents up to 4A. It has a typical line regulation of 0.07 %/V, load regulation of 0.1 %/A, and quiescent current of 10uA at no-load. The output voltage is set by a single external resistor, making it very easy to adjust. In conclusion, the SPX1582T5-L is an ideal choice for bus systems, processors and other electronic circuits requiring low noise and less power dissipation.
