The S-1131B28UA-N4NTFU is a three-terminal adjustable voltage regulator device which is used for controlling of the output voltage, current, and power by varying the feedback network between its output pin and the comparison amplifier. It belongs to the family of PMIC (Power Management Integrated Circuits) Voltage Regulators and more accurately, belongs to the class of linear voltage regulators.

The device primarily consists of an error amplifier, a series pass regulator, and an internal voltage reference, all integrated together in one component. This component is usually mounted on a circuit board and is then connected to the entire power management network of the system. Depending on the system\'s requirement, the component can be used as either a fixed voltage regulator or as an adjustable voltage regulator.

To use the component as a fixed voltage regulator, the output voltage can be adjusted to a given level by connecting the feedback pins to the start pin. The component will then behave as a zener diode and the output voltage can be varied by varying the connecting resistor at the input pin. The component can also be used as an adjustable voltage regulator wherein the output voltage is controlled by the voltage at the output pin. By varying this voltage, the output voltage can also be varied.

The S-1131B28UA-N4NTFU works by comparing the voltage at the output pin and the internal reference voltage. If these two voltages are different, the error amplifier will produce the required output current to maintain the output voltage. The series pass regulator then acts as an amplifier and amplifies the output current from the error amplifier to set the output voltage.

The S-1131B28UA-N4NTFU is a three-terminal adjustable voltage regulator device which is utilized in applications to control a variety of electronic products, such as computers, laptops, cellular phones, LED displays, and many more. The width of the output voltage range provided by the device is adjustable, making it suitable for controlling the output voltage of a number of different devices.
