TLVH431NMQDBZRR

Overview

The TLVH431NMQDBZRR is a three-terminal adjustable precision shunt regulator from the Nexperia TLVH431N family. It operates within a cathode-anode voltage range of Vref to 14 V, with output voltage set by two external resistors. The device features a reference voltage tolerance of 1.5% (Standard Grade) and supports a sink current capability from 0.08 mA to 70 mA. It utilizes mirrored pinning in an SOT23 package.

Feature Summary

Programmable output voltage up to 14 V
Low output noise characteristics
Typical output impedance of 0.1 Ω
Mirrored pin configuration for SOT23

Applications

Shunt regulator
Precision current limiter
Precision constant current sink
Isolated feedback loop for Switch Mode Power Supply (SMPS)

Procurement Notes

Verify that the specific suffix 'R' indicates tape-and-reel packaging as distinct from standard reel quantities. Confirm the component is non-automotive qualified per the Rev 3 datasheet update. Ensure design compatibility with the mirrored pinout configuration required by this specific part number variant.

Selection Notes

Select this model when a mirrored pin configuration is necessary for PCB layout optimization. The Standard Grade offers a 1.5% reference voltage tolerance suitable for general-purpose applications. Verify thermal stability requirements against the -40 °C to 125 °C operating range specified for the QDBZR series.

Part Context

This component belongs to the TLVH431N family of low-voltage adjustable precision shunt regulators. It serves as a replacement for Zener diodes in on-board regulation and adjustable power supplies. The family includes variants with normal and mirrored pinning configurations across different temperature grades.
