TLV431BIDBZRG4: Precision Low-Voltage Shunt Regulator
The TLV431BIDBZRG4 is a high-quality, precision low-voltage shunt regulator manufactured by Texas Instruments. This device is designed to provide a reliable, adjustable output voltage with a low threshold voltage of 1.24V, which can be set to any value between Vref (approximately 1.24V) and 6V using two external resistors. The TLV431BIDBZRG4 offers excellent temperature stability and low output noise, making it suitable for a wide range of applications, including power supply control and voltage monitoring.
This versatile component is characterized by its low dynamic output impedance, which ensures stable operation even with varying load conditions. The impedance of 0.22 ohms (typical) combined with a fast turn-on response provides excellent transient response characteristics. The TLV431BIDBZRG4 is capable of sourcing up to 100mA of output current, and it has a typical output tolerance of ±0.5% at 25°C, which ensures precise voltage regulation in critical applications.
The device is offered in a small surface-mount package, specifically the SOT-23 (DBZ) package, which is ideal for space-constrained applications. The TLV431BIDBZRG4 also features a wide operating temperature range of -40°C to 85°C, allowing it to perform reliably in a variety of environments and conditions.
With its low quiescent current, this shunt regulator is also an excellent choice for battery-powered applications where power efficiency is crucial. The design facilitates easy compensation, minimal external components, and simple implementation, making it a go-to solution for designers looking to improve the performance of their power management systems.
Overall, the TLV431BIDBZRG4 from Texas Instruments represents a robust and versatile solution for applications requiring precise voltage regulation. Its combination of features, including low voltage operation, high accuracy, and compact form factor, make it an essential component for power supply designs in industrial, consumer, and portable electronics.
