TLVH432BQDBZR

Overview

The TLVH432BQDBZR is a low-voltage adjustable precision shunt regulator manufactured by Texas Instruments. It operates within a supply voltage range up to 20 V and provides an adjustable output voltage up to 18 V. The device features an initial accuracy of 0.5% and a temperature coefficient of 138 PPM/°C. Maximum cathode current is 80 mA, with a minimum operating current of 80 µA. It functions across an extended temperature range from -40°C to +125°C. The component is housed in a SOT-23-3 surface-mount package and is supplied in reel, cut tape, or MouseReel formats.

Feature Summary

Adjustable precision shunt regulation with high initial accuracy
Extended industrial temperature operation capability
Low minimum cathode current for efficient light-load performance

Applications

Battery-powered portable equipment
Microcontroller power supply monitoring
Linear regulator reference voltage sources
Overvoltage protection circuits

Procurement Notes

Verify the specific suffix 'B' indicates the 0.5% accuracy grade distinct from standard variants. Confirm the 'Q' prefix denotes automotive qualification requirements if applicable to the target design. Ensure the SOT-23-3 package orientation matches the PCB footprint. Check RoHS compliance status against regional regulatory standards before finalizing procurement.

Selection Notes

Select this part when high precision and wide temperature stability are required in a compact surface-mount form factor. The low minimum cathode current makes it suitable for battery applications where standby power consumption must be minimized. Compare against standard TLVH432 variants if automotive qualification or tighter tolerance specifications are not strictly necessary for the application.

Part Context

This component belongs to the TLVH432 family of low-voltage shunt regulators designed for precision reference applications. It serves as a cost-effective alternative to Zener diodes, offering superior temperature stability and lower dynamic impedance. The family includes various accuracy grades and packaging options to support diverse industrial and consumer electronics designs requiring reliable voltage referencing.
