The TL431BQDR is a three-terminal adjustable shunt regulator family with a fixed output voltage of 2.5V and an adjustable output voltage up to 36V. The TL431BQDR family includes 5 different versions, each with a ±15%, 10%, 5% and 2% initial accuracy tolerance, making it easy to obtain the desired output voltage. The TL431BQDR family also has low current threshold and low saturation voltage characteristics, low temperature drift (not more than 5ppm/°C) and a fast response time of 1.4 μs.

The TL431BQDR is part of the PMIC (Power Management IC) family and classified as a voltage reference device. Voltage reference devices are used to maintain a pre-set stable voltage for any off-line power convertor or power monitoring system. Most of the time a microcontroller or FPGA (Field Programmable Gate Array) is used to monitor the voltage output of the voltage reference device, and adjust the output accordingly.

The TL431BQDR works by controlling the output voltage level by varying the output current. During normal operation the output voltage will be maintained at the set voltage. When a voltage greater than the output voltage is applied to the input, the current is increased to reduce the output voltage. When a voltage lower than the output is applied, the current is decreased, increasing the output voltage.

The TL431BQDR also has a wide range of application fields, such as for power supply stability, power supply regulation, power monitoring, over voltage and under voltage protection, and current regulation control. These features make it ideal for power supply and monitor designs, such as power adapter circuits, battery charging, and power management systems.

The TL431BQDR family also provides a very low cost and high efficiency solution for many applications. The integrated chip package provides an easy to use, low component count solution that is ideal for saving both time and cost for a variety of applications, especially in consumer electronics.

The TL431BQDR is also one of the most versatile voltage reference devices available. It has adjustable operating input voltages and a wide operating temperature range of -40 to +125 °C. These features make the TL431BQDR especially suitable for low cost and low power applications, such as battery powered systems.

In summary, the TL431BQDR is a very versatile and efficient voltage reference device, making it ideal for a wide range of applications. With low component count, low cost and low power consumption, it is the perfect solution for many consumer electronics and industrial designs.
