TL431BQDBZRG4

Overview

The TL431BQDBZRG4 is an adjustable precision shunt regulator from Texas Instruments, housed in a SOT-23-3 surface-mount package. It provides an adjustable output voltage range from 2.495 V to 36 V with an initial accuracy of 0.5%. The device supports a maximum cathode current of 100 mA and requires a minimum operating current of 600 µA. It operates within a temperature range of -40°C to +125°C and features a maximum temperature coefficient of 92 PPM/°C. The component is designed for automotive applications, ensuring reliability under varying thermal conditions.

Feature Summary

Provides precise voltage regulation with 0.5% initial accuracy for stable reference performance
Supports wide input voltage ranges up to 36 V for flexible circuit integration
Automotive-grade qualification ensures robust operation in demanding environments

Applications

Automotive power supply circuits requiring high reliability
Precision voltage references in industrial control systems
Battery management systems needing accurate monitoring

Procurement Notes

Verify the specific suffix RG4 indicates tape and reel packaging configuration. Confirm automotive grade status through official datasheets. Check RoHS compliance details as specified by manufacturer documentation. Ensure compatibility with existing PCB footprint designs before procurement.

Selection Notes

Select this component when automotive qualification and high precision are required. Compare against standard TL431 variants if industrial grade suffices. Consider SOT-23-3 package constraints for space-limited designs. Evaluate thermal management needs given the wide operating temperature range.

Part Context

This part belongs to the TL431 family of adjustable shunt regulators. It shares functional similarities with other TL431 variants but differs in packaging and automotive qualification. The QDBZR suffix denotes automotive grade and specific packaging options.
