TLVH431AIDBZRG4

Overview

The TLVH431AIDBZRG4 is a low-voltage adjustable precision shunt regulator manufactured by Texas Instruments. It operates within a supply voltage range of up to 20 V and provides an adjustable output voltage from 1.24 V to 18 V. The device features an initial accuracy of 1% and a temperature coefficient of 138 PPM/C. It supports a maximum cathode current of 80 mA with a minimum operating current of 80 uA. The component functions reliably across an extended temperature range from -40°C to +125°C and is housed in a compact SOT-23-3 surface-mount package.

Feature Summary

Provides precise adjustable voltage regulation with 1% initial accuracy for stable reference applications
Operates at low voltages with a wide input range supporting up to 20 V series connection
Designed for high thermal stability with a low temperature coefficient over the industrial temperature range

Applications

Precision voltage references in portable electronic devices
Feedback control loops in switching power supplies
Battery-powered equipment requiring stable reference voltages

Procurement Notes

Verify the complete part number including the G4 suffix, which indicates lead-free and RoHS compliance status. Confirm the specific tape-and-reel packaging configuration required for automated assembly processes. Ensure the ordering quantity aligns with standard reel sizes or cut-tape availability to match production line requirements accurately.

Selection Notes

Select this component when a low-voltage adjustable shunt regulator with high accuracy is required. The SOT-23-3 package offers space efficiency for dense PCB layouts. Consider the 80 mA cathode current capability for driving loads directly. Verify that the operating environment stays within the specified -40°C to +125°C temperature limits for optimal performance.

Part Context

This device belongs to the TLVH431 family of low-voltage adjustable precision shunt regulators. It serves as a modern alternative to traditional Zener diodes, offering superior voltage stability and lower impedance characteristics. The family includes variants with different accuracy grades and automotive qualifications, catering to diverse industrial and consumer electronics needs.
