PMIC - Voltage Reference is an essential component for the successful operation of any system. The REF198FS-REEL integrated circuit from Texas Instruments is one such voltage reference, used in a wide variety of applications. This article will discuss the application field and working principle of the REF198FS-REEL. Technologically speaking, the REF198FS-REEL is a monolithic shunt voltage reference which provides a reference voltage for any application. It is a fully-featured device, which features low temperature drift, low noise, low leakage current and high accuracy, making it a great choice for many power management applications. Its accuracy is guaranteed to ±0.1% over a wide temperature range, and its low output noise ensures that the device will not cause any unwanted noise in the system.Typical applications of the REF198FS-REEL include but are not limited to powering digital circuits, analog-to-digital converters, motor control systems, audio systems and power supply regulation circuits. The device is often used as a voltage reference in combination with an adjustable voltage regulator, where the REF198FS-REEL provides the reference voltage and the adjustable regulator circuit is used to regulate the voltage to the desired level. This combination is especially useful when the circuit needs to be very accurate, as the inherent accuracy of the REF198FS-REEL will be transferred to the adjustable voltage regulator.When used in shunt regulator applications, the REF198FS-REEL provides an output voltage that is stable and well-regulated. The device features a built-in droop capability that increases the output current capability and reduces power supply overshoot and undershoot. To further improve its performance, the REF198FS-REEL also features a built-in temperature sensing device, which helps keep the output voltage stable over temperature changes.The working principle of the REF198FS-REEL is relatively straightforward. The device consists of a bandgap voltage reference, which generates a reference voltage between its two terminals. This reference voltage is further fed to an adjustable current source, which is used to determine the output current of the device. This current source can be adjusted to generate a precise and constant output voltage, which will then be provided to the output of the device. The output voltage can also be adjusted by adding external resistors or capacitors to the REF198FS-REEL.In summary, the REF198FS-REEL is a monolithic shunt voltage reference integrated circuit which provides a reference voltage for any application. It is widely used in digital circuits, motor control systems, audio systems and power supply regulation circuits, as its inherent accuracy and low output noise make it an ideal choice for many power management applications. Its working principle is based on a bandgap voltage reference which is fed to an adjustable current source, and its output voltage can be adjusted using external resistors or capacitors.The specific data is subject to PDF, and the above content is for reference
