The TL431ILP* family of adjustable shunt regulators employs a closed loop voltage referencing system. This type of device is typically used in power supply, battery charging and other applications requiring precise voltage control. It is a three-terminal device, with an adjustable output voltage pin, a feedback input pin, and a reference voltage input pin. The TL431ILP* family of adjustable shunt regulators is a key component in many PC, home entertainment and other consumer electronic systems.

The TL431ILP* family’s features and benefits include high accuracy, excellent temperature stability and high power dissipation. The low on-chip reference voltage and current sensing feature makes them well-suited for application in high current applications such as used in battery charging. Additionally, the devices have a very low profile package, which allows them to be placed in tight spaces.

The working principle of TL431ILP* devices requires the use of two internal comparators. One of the comparators is used to track the reference voltage (Vref), while the second comparator monitors the feedback voltage (Vfb). When the feedback voltage is greater than the reference voltage, the higher voltage will be connected to the output pin. If the reference voltage is greater than the feedback voltage, the lower voltage will be connected to the output pin. By varying the reference voltage, an adjustable output voltage can be achieved.

The TL431ILP* family of adjustable reference devices provides a wide range of output voltages and is designed to meet the demands of numerous applications. These devices are used in a variety of electronic systems, from mobile phones, laptops and tablets, to household appliances and monitoring systems. The versatile design and wide range of output voltages make the TL431ILP* an ideal choice for many precision power supply design applications.

The TL431ILP* family of adjustable reference devices is also typically employed in automotive applications. These devices are used to ensure accurate voltage regulation in fuel injection, engine control and timing systems. The devices are also used to monitor battery charge and discharge levels in automotive battery management systems. Furthermore, they are utilized in various systems of in-car entertainment electronics, such as car audio and multimedia systems.

The TL431ILP* family of devices is a perfect fit for power management, mobile devices, industrial and automotive applications. These devices offer a wide variety of features such as high accuracy, excellent temperature stability and an extremely low profile package, which makes them ideal for space-critical designs. Additionally, the adjustable output voltage, combined with the two-comparator design, provides precise voltage control. This makes them well-suited for applications requiring accurate voltage control. As a result, the TL431ILP* family of adjustable shunt regulators is a key component in many PC, home entertainment and other consumer electronic systems.
