TLVH432QDBZR

Overview

The TLVH432QDBZR is an adjustable precision shunt voltage reference manufactured by Texas Instruments. It operates within a supply voltage range of 2.5 V to 20 V and provides an adjustable output voltage from 1.24 V to 18 V. The device features an initial accuracy of 1.5% and a temperature coefficient of 138 ppm/°C. It supports a cathode current range of 80 µA to 80 mA, with a typical dynamic impedance of 0.22 Ω. The component is housed in a SOT-23-3 package and is rated for operation between -40°C and +125°C.

Feature Summary

Adjustable output voltage capability spanning from 1.24 V up to 18 V
High precision performance with 1.5% initial accuracy tolerance
Wide operating current range supporting low-power and high-load applications

Applications

Portable battery-powered equipment requiring precise voltage regulation
Data acquisition systems needing stable reference voltages
Microcontroller power supply monitoring circuits
Battery chargers and management systems

Procurement Notes

Verify the specific suffix 'Q' indicates automotive qualification status if required by your design specifications. Confirm the 'R' suffix corresponds to tape-and-reel packaging for automated assembly processes. Ensure the selected variant matches the required accuracy grade and thermal performance for your intended operating environment.

Selection Notes

Select this component when a compact, low-voltage adjustable reference is needed with moderate precision requirements. Compare against TLVH432AQDBZR for tighter 1% accuracy or TLVH432BQDBZR for improved temperature stability. Consider the SOT-23-3 footprint constraints and the 80 mA maximum sink current capability during circuit design.

Part Context

This part belongs to the TLVH432 family of low-voltage adjustable shunt regulators. It shares pinout compatibility with other devices in the series but differs in accuracy grades and temperature coefficients. The QDBZR designation specifies the automotive-grade quality level and reel packaging format within the broader Texas Instruments voltage reference portfolio.
