The TL431AIDBZT is a three-terminal integrated circuit (IC) in the Voltage Reference family of programmable shunt regulators. It is specifically a low drop out adjustable voltage reference with a wide range of applications. The device comprises of a Zener diode, an operational amplifier, and a temperature compensating circuit. The TL431AIDBZT is one of the most commonly used voltage references due to its low voltage drop, high accuracy, and temperature stability.

The TL431AIDBZT operates as a voltage regulator by using an internal reference voltage, which is compared to an externally applied voltage. This voltage comparison is used to adjust an output voltage. It does not require an external reference source and thus, is widely used in battery-powered devices. The TL431AIDBZT can be varied over a range of approximately 1.2 to 37V by simply changing the feedback resistor. This allows the user to easily adjust the output voltage from the device over a wide range. Additionally, the device has excellent temperature stability, operating temperature range of -40°C to +125°C, and can provide up to 30mA current output.

The TL431AIDBZT is often used to provide a stable reference voltage in wide variety of applications, including: voltage references, battery chargers and supervisor circuits, secondary side feedback in switching power supplies, overvoltage and undervoltage protection circuits, current-mode controllers, and instrumentation amplifiers. It is also used as an adjustable power supply, controlling the current and the temperature. The device is available in TO-220 and SOT-223 packages.

The TL431AIDBZT is a simple and cost-effective solution for providing an adjustable and stable voltage reference. The output voltage is adjustable over a wide range and it also has excellent temperature stability and reliability due to its on-chip temperature compensation circuit. The device is also easy to use and does not require an external reference source. This makes the TL431AIDBZT an ideal choice for a wide range of voltage reference applications.
