Overview
The TLV431BQDBZTG4 is a low-voltage adjustable precision shunt regulator from Texas Instruments, designed for automotive applications. It operates with an output voltage range of 1.24 V to 6 V and provides an initial accuracy of ±0.5%. The device supports a maximum cathode current of 15 mA and functions within a temperature range of -40°C to +125°C. Packaged in a compact SOT-23-3 surface-mount format, it serves as a stable reference voltage source in power management circuits.
Feature Summary
- Automotive-grade reliability compliant with AEC-Q100 standards
- Low-voltage operation optimized for battery-powered systems
- High precision with tight initial accuracy tolerance
Applications
- Battery monitoring and protection circuits
- Precision voltage references in automotive ECUs
- Low-dropout linear regulator feedback networks
Procurement Notes
Verify the specific suffix 'G4' indicates lead-free packaging and RoHS compliance per Texas Instruments documentation. Confirm the automotive qualification status matches project requirements. Ensure the SOT-23-3 package dimensions align with PCB footprint constraints. Check for any recent lifecycle notices regarding obsolescence or alternative recommendations.
Selection Notes
Select this component when a low-voltage, high-precision reference is required in space-constrained automotive designs. The SOT-23-3 package offers a small footprint suitable for dense layouts. Consider the 15 mA current limit for load requirements. Verify that the 1.24 V to 6 V adjustment range covers the target application voltage needs.
Part Context
This part belongs to the TLV431 family of adjustable shunt regulators. It is specifically qualified for automotive use, distinguishing it from standard industrial variants. The device complements other TI voltage references by offering a balance of precision, low voltage operation, and automotive durability in a miniature package.
Replacement Considerations
Check for direct equivalents such as TLV431AIDBZRQ1 or TLV431BIDBVRQ1 if pin compatibility and electrical specifications match. Ensure any substitute maintains the same automotive grade and package type.
