The TL431BCDBZRVL is a three-terminal adjustable shunt regulator of the Adjustable Voltage Reference (AVR) type device, used primarily in power management applications. It is often used in consumer and professional audio/video systems, industrial applications and computer power supplies. The TL431BCDBZRVL is capable of replacing many standard fixed and adjustable voltage regulators, such as the LM317 and LM723 series. The TL431BCDBZRVL consists of an integrated precision reference and an adjustable amplifier with a large dynamic output range. The precision reference is programmed with two small external resistors, issuing an accurate reference voltage between 1.25V and 36V. The output voltage is adjusted or monitored by an internal amplifier stage. This allows closed-loop control of the output voltage with precise regulation.The TL431BCDBZRVL features a high ripple rejection to suppress noise and line variations. It is also capable of accurately regulating the output voltage over a wide range of temperatures. The device is also capable of over-voltage protection, allowing it to be used in conjunction with switching power supplies and other circuits where precise voltage regulation is required. The TL431BCDBZRVL can be used in a wide range of applications, such as load regulation, battery charging, negative supply regulation, linear or switching power supplies, audio/video equipment, LED lighting and LED displays. The device is used in a variety of systems and equipment, including computers, TVs, gaming systems, appliances, servers, scientific instrumentation, medical equipment and industrial control systems. The device enables users to program the output voltage by changing the voltage divider ratio. This allows users to set a precise output voltage and eliminate the need for an additional reference voltage source. Additionally, the device has a low capacitor value output and a very low temperature coefficient of 0.015%.The rapid rise in the development of digital technology means that the power supply has to cope with stringent voltage regulation requirements. The TL431BCDBZRVL is capable of accurately regulating the output voltage over a wide output voltage and temperature range, thus making it ideal for applications such as computers and digital equipment that demand precise voltage regulation. In summary, the TL431BCDBZRVL is an adjustable shunt regulator of the AVR type device, used primarily in power management applications such as computers, TVs and gaming systems. The device enables users to set a precise output voltage by changing the voltage divider ratio and it is capable of accurately regulating the output voltage over a wide range of temperatures and over-voltage protection. In addition, the device features high ripple rejection to suppress noise and line variations, a low capacitor value output and a very low temperature coefficient. As such, the TL431BCDBZRVL is an ideal voltage reference for a wide range of applications that demand precise voltage regulation.
