Linear voltage regulators are an important part of power management integrated circuit (PMIC) systems. The S-13R1F35-N4T1U3 is one such regulator, and is a voltage regulator for negative voltage output applications. The S-13R1F35-N4T1U3 features low dropout voltage, low output noise, and is capable of a wide range of output voltages. This makes it an ideal retail system and industrial control applications, as well as automotive, drone, and mobile device applications.

Features

The S-13R1F35- N4T1U3 has a variety of features, including adjustable output voltage, low noise, and adjustable input voltage range. The adjustable output voltage allows for a wide range of output voltages, from 1 V to -13 V. The low noise is designed to minimize interference and keep the output voltage level within a few millivolts with a low output noise, within a maximum of 2 mV. The adjustable input voltage range is from -30 V to -3.3 V.

Working Principle

The S-13R1F35-N4T1U3 is based on the linear voltage regulation principle, which utilises the Zener voltage drop of a PN junction as its primary regulating element. The Zener diode is connected in a series with a load and a fixed power source to maintain the output voltage at a predetermined level. The output voltage is adjusted by the voltage drop across two series diodes, which are connected in reverse parallel to the Zener diode. The diodes prevent the output voltage from going any higher than the limiting voltage that is associated with the Zener diode, while the voltage drop on the series diodes regulates the output voltage. Because the Zener diode is also in series with the output, it provides input protection against short circuits and high-voltage spikes.

Application Field

The S-13R1F35-N4T1U3 is popular in several applications due to its adjustable output voltage range and low noise. For example, it is particularly useful for industrial control and retail systems where precise control of the output voltage is necessary. It is also used in automotive applications such as drones and electric vehicles, where precise control of the output voltage is paramount. The low noise features of the S-13R1F35-N4T1U3 make it perfect for applications in mobile devices, such as smartphones and tablets, where the device must remain free of interference.

Conclusion

The S-13R1F35-N4T1U3 is a linear voltage regulator for negative voltage output applications. It features adjustable output voltage, low noise, and adjustable input voltage range for precise output voltage control.
