TLVH431BIDBZRG4

Overview

The TLVH431BIDBZRG4 is an automotive-grade, low-voltage adjustable precision shunt regulator manufactured by Texas Instruments. It operates within a supply voltage range of 2.5 V to 18 V and provides an adjustable output voltage from 1.24 V to 18 V. The device features a typical initial accuracy of ±0.5% and supports a maximum cathode current of 70 mA. It is designed for operation across an extended temperature range of -40°C to +125°C. The component utilizes a SOT-23-3 surface-mount package and complies with AEC-Q100 standards for automotive applications.

Feature Summary

Automotive qualification compliant with AEC-Q100 standards for reliability in vehicle environments
Low-voltage operation capability starting at 2.5 V supply voltage
High precision reference performance with ±0.5% initial accuracy tolerance
Wide operating temperature range extending up to +125°C

Applications

Voltage reference sources in automotive electronic control units
Precision voltage regulation in automotive power management circuits
Feedback network components in automotive DC-DC converters
Comparator references in automotive sensor signal conditioning

Procurement Notes

Verify the complete part number including the G4 suffix to ensure compliance with RoHS directives and lead-free manufacturing requirements. Confirm that the specific revision matches the intended automotive application specifications. Check datasheet revisions for any updates regarding marking codes or packaging details before finalizing procurement orders.

Selection Notes

Select this component when automotive reliability certification is mandatory for the design. The ±0.5% accuracy suits applications requiring tighter tolerance than standard TLV431 variants. Ensure the circuit design accommodates the 70 mA maximum cathode current limit. Verify that the SOT-23-3 package footprint aligns with the PCB layout constraints.

Part Context

This device belongs to the TLVH431 family of low-voltage adjustable shunt regulators. The 'B' designation indicates the ±0.5% accuracy grade, distinguishing it from lower accuracy variants. The 'Q1' suffix denotes its qualification for automotive use under AEC-Q100 standards. It serves as a high-reliability alternative to non-automotive precision references in demanding vehicular electronics.
