The TLVH431AQDBZR is a high-voltage, precision micropower shunt regulator manufactured by Texas Instruments. It is designed to provide a stable output voltage with low quiescent current, making it ideal for a wide range of applications that require precise voltage regulation.

Description:

The TLVH431AQDBZR is a fixed-output, low-dropout (LDO) linear voltage regulator with an output voltage of 2.5V. It is available in a small, thermally enhanced QFN package, making it suitable for space-constrained applications.

Features:

1. Low quiescent current: The TLVH431AQDBZR has a very low quiescent current of typically 2.5µA, which helps to extend the battery life in portable devices.
2. High input voltage range: The LDO can handle input voltages up to 60V, making it suitable for applications with high input voltages.
3. Precision output voltage: The output voltage accuracy is typically ±1%, ensuring a stable and precise output voltage.
4. Low dropout voltage: The dropout voltage is typically 1.5V at full load, which means it can efficiently regulate the output voltage even when the input voltage is close to the output voltage.
5. High PSRR: The TLVH431AQDBZR has a high power supply rejection ratio (PSRR) of typically 80dB at 1kHz, providing excellent noise rejection and stability.
6. Thermal protection: The LDO features an over-temperature protection feature that limits the die temperature to a safe level.

Applications:

1. Portable devices: Due to its low quiescent current and high input voltage range, the TLVH431AQDBZR is well-suited for use in portable devices such as smartphones, tablets, and wearables.
2. Industrial equipment: The LDO can be used in industrial equipment that requires precise voltage regulation, such as sensors, controllers, and motor drivers.
3. Medical devices: The TLVH431AQDBZR can be used in medical devices that require stable and precise voltage regulation, such as patient monitoring equipment and diagnostic devices.
4. Automotive applications: The LDO can be used in automotive applications that require a stable voltage supply, such as infotainment systems, sensor interfaces, and power management systems.
5. Battery-powered devices: The low quiescent current of the TLVH431AQDBZR makes it ideal for use in battery-powered devices, helping to extend battery life.

In summary, the TLVH431AQDBZR is a high-voltage, precision micropower shunt regulator that offers low quiescent current, high input voltage range, and excellent stability. Its features make it suitable for a wide range of applications, including portable devices, industrial equipment, medical devices, automotive applications, and battery-powered devices.
