The S-1131B38UA-N4XTFU voltage regulator is part of Mitsubishi’s S-1131 series of linear regulators. It is a 3-terminal, very low dropout, low output noise regulator with an adjustable output voltage from 0.8V to 5.3V. The output voltage is set by a single external resistor and remains stable with a +-0.4% accuracy even in the presence of varying temperatures and load conditions.The S-1131B38UA-N4XTFU’s application field can be found in a wide variety of systems that require low power, reliable, and precise voltage regulation. Such systems include cellular phones and other portable devices, notebooks and touch panels, as well as industrial control systems, avionics and automotive components.

The S-1131B38UA-N4XTFU’s working principles are based on the well-known voltage regulator design principle. It is designed to work as a linear regulator in order to regulate the output voltage. This is done by sensing the output voltage and then adjusting the input voltage as necessary to maintain the specified output voltage. The voltage regulator also provides protection for the device against over-voltage, over-temperature, and inrush current.

The S-1131B38UA-N4XTFU features MOSFET pull-up pass elements, which are necessary for the effective regulation of output voltages. This type of element allows the device to work in areas where there may be high levels of noise, because the pass element is able to keep the unwanted currents away from the supply and the sensitive parts. As a result, there is no loss of accuracy and reliability.

The S-1131B38UA-N4XTFU also has an advanced control circuit, which is responsible for the low dropout, low output noise, and temperature compensation. The control circuit utilizes a range of voltage reference components, such as resistors, capacitors, and diodes, and it is designed to precisely control the output voltage. This ensures that the output voltage remains within the desired range.

The voltage regulator also features a wide operating temperature range between -40°C and +85°C, making it suitable for a wide range of applications. In addition, the device can be used in environments where high humidity and/or temperature fluctuations are present. This ensures the reliable operation of the device in challenging operating conditions.

In conclusion, the S-1131B38UA-N4XTFU is ideal for powering medium- to low-power applications which require precise and reliable voltage regulation. Its wide operating temperature range and robust design make it suitable for a broad range of applications, while its low dropout, low output noise, and temperature compensation features ensure that it delivers ideal performance in challenging environments.
