TLVH431AQDBVR,125

Overview

The TLVH431AQDBVR,125 is a low voltage three-terminal shunt regulator from the NXP TLVH431 family. It features an A-Grade reference voltage tolerance of 1% and operates within a temperature range of -40 °C to +125 °C. The device utilizes a SOT753 (SC-74A) surface-mount package with five leads. Output voltage is programmable between Vref (approximately 1.24 V) and 18 V using two external resistors. It supports cathode currents from 0.08 mA to 70 mA and includes AEC-Q100 Grade 1 qualification for automotive reliability.

Feature Summary

• A-Grade precision with 1% reference voltage tolerance
• Automotive-grade qualification under AEC-Q100 standards
• Wide operating temperature range suitable for harsh environments
• Low output noise and dynamic impedance characteristics

Applications

• Shunt regulator circuits
• Precision current limiter designs
• Precision constant current sink implementations
• Isolated feedback loops for Switch Mode Power Supplies

Procurement Notes

Verify that the ordering suffix ,125 corresponds to the specified packing method in the official documentation. Confirm the component matches the SOT753 package outline and pin configuration defined for the TLVH431AQDBVR part number. Ensure the requested grade aligns with the required 1% tolerance specifications for the design application.

Selection Notes

Select this variant when a 1% reference voltage accuracy is required alongside extended temperature coverage up to 125 °C. The SOT753 package provides a compact footprint compared to standard SOT23 options. Consider the mirrored or normal pinning requirements if substituting other family members, though this specific part follows the standard configuration for the AQDBVR designation.

Part Context

This component belongs to the TLVH431 family of low voltage adjustable precision shunt regulators manufactured by NXP Semiconductors.
