The TL431BQLP is a voltage reference that belongs to the PMIC (Power Management Integrated Circuit) category. This voltage reference provides a circuit that enables the accurate and convenient production of a precise output voltage without external circuitry. It is able to maintain a steady output voltage even when the input voltage or load current changes.

The TL431BQLP is a three-terminal adjustable voltage reference. It has a wide range of operating temperature and power supply voltage, which makes it suitable for various operation conditions. Its high stability and accuracy makes it an ideal solution for many applications. The main advantage of this voltage reference is that it can produce a voltage output that is within 2% of a predetermined reference voltage. This in turn provides accurate and stable voltage control over a wide range of load current, temperature, and power supply voltage.

The working principle of the TL431BQLP is based on the Output Voltage Pass (OVP) principle. This principle utilizes the equations and models of a simple N-type MOSFET to generate an output voltage that is multiple times higher than the reference voltage. The OVP principle takes advantage of the phenomenon that when a voltage applied to the gate of a FET is equal to its substrate voltage, the output current is equal to the current that is flowing through the gate. This allows the voltage reference to control the output voltage accurately, even when the input voltage changes.

The TL431BQLP is most commonly used in applications such as microprocessors, power supplies, audio systems and low voltage applications. It can be used to provide precise control over the output voltage of a system, helping to ensure that the device is safe to use in harsh operating conditions. In addition, the TL431BQLP is also used for temperature compensation, providing temperature stability to maintain an accurate output voltage even in extreme condition.

In summary, the TL431BQLP is a voltage reference that belongs to the PMIC (Power Management Integrated Circuit) category. It has a wide range of operating temperature and power supply voltage, which makes it suitable for many applications. Its Output Voltage Pass (OVP) principle makes it able to offer accurate output voltage control even when the input voltage or load current changes. The TL431BQLP can be used in a variety of applications, including microprocessors, power supplies, audio systems, low voltage applications and temperature compensation.
