The TLVH431ACDBVR is an adjustable precision shunt regulator manufactured by Texas Instruments, used to provide a reference voltage which can be programmed by an external resistor divider network. It has been designed with an extensive array of protection features and is intended for use in voltage regulation applications.

The TLVH431ACDBVR is part of the PMIC - Voltage Reference family. With its precision oscillator, it can operate at frequencies up to 1 MHz, depending on the external resistor components. The TLVH431ACDBVR can operate from either a single or dual power supply as it is capable of both positive and negative output voltage ranges. It also has a high bandwidth, low output impedance and tight voltage reference accuracy of 1%.

The primary use of the TLVH431ACDBVR is for precision voltage reference applications. It can be used to maintain a steady voltage reference for applications such as power supplies, controllers, and regulators. It can also be used to measure voltage drop or spikes in a circuit and protect sensitive components from damage caused by over-voltage. It is also used in automotive and industry applications such as voltage monitoring and regulation.

The TLVH431ACDBVR operates by maintaining a constant output voltage as the load current varies. An internal reference voltage is established by two resistors connected between output voltage terminals. When current flows through the two resistors, it generates a differential voltage that is compared to the internal reference voltage. This differential voltage is then turned into an output voltage which can be adjusted by changing the external resistor divider network. The output voltage is then monitored to ensure that it does not exceed predetermined values.

The internal reference voltage also serves as an adjustable voltage divider for the external components connected to the output voltage terminals. By varying the value of the external resistor divider, the internal reference voltage is adjusted to the desired output voltage. As the load current changes, the internal reference voltage can be automatically adjusted to maintain a steady output voltage. This ensures that the output voltage stays within the predetermined range, regardless of the load current.

In addition to providing an adjustable reference voltage, the TLVH431ACDBVR also offers protection features. It is designed with a frequency foldback feature, which modulates the output voltage when it is above or below the predetermined range. This feature protects components from over-voltage and over-current, while also reducing power losses. It also has a reset input, which enables it to reset itself automatically if the output voltage exceeds the programmed voltage value.

The TLVH431ACDBVR is a cost-effective, versatile device with an extensive range of features and applications. It can be used in a variety of voltage regulation applications to ensure precise voltage measurement and protection for sensitive components. The adjustable precision shunt regulator is designed to provide precise reference voltage and protection for applications and is suitable for use in industrial and automotive applications.
