TLVH431QDBVR Adjustable Precision Shunt Regulator by Texas Instruments

The TLVH431QDBVR is a high-performance, low-voltage adjustable precision shunt regulator from Texas Instruments designed for voltage regulation in a wide range of applications. This device is part of Texas Instruments' extensive portfolio of voltage references and regulators, known for their reliability and precision.

The TLVH431QDBVR offers a minimum cathode current requirement as low as 70µA, which is beneficial for low-power operations. It allows for an adjustable output voltage from 1.24V to 18V with an initial reference voltage precision of 1%. This makes it incredibly versatile for various applications where precise voltage control is necessary.

One of the key features of the TLVH431QDBVR is its low output noise, which makes it suitable for sensitive electronics where noise can be a critical factor, such as precision instrumentation, data acquisition systems, and industrial controls. Additionally, the device has a typical temperature coefficient of only 50ppm/°C, ensuring stable performance over a wide temperature range.

The TLVH431QDBVR comes in a small SOT-23-5 package, which is ideal for space-constrained applications. Its small size does not compromise its performance, as it can handle a wide operating current range from 70µA to 70mA. The device's design also includes a stable reverse breakdown voltage, ensuring reliable operation even under transient conditions.

For protection, the TLVH431QDBVR incorporates an overcurrent protection mechanism that helps prevent damage to the device under extreme operating conditions. This feature, along with its excellent thermal stability, contributes to the longevity and durability of the regulator.

Whether you are designing power supplies, portable electronics, or adjusting voltage references, the TLVH431QDBVR from Texas Instruments is an excellent choice for maintaining precise voltage regulation in a compact, efficient, and reliable package.
