TLVH432BCDBZRG4

Overview

The TLVH432BCDBZRG4 is an adjustable precision shunt regulator from Texas Instruments, housed in a SOT-23-3 package. It features an initial accuracy of 0.5% and operates within a temperature range of -40°C to +125°C. The device supports an output voltage range up to 18 V with a maximum input voltage of 20 V. It draws a minimum cathode current of 80 µA and can handle a maximum shunt current of 80 mA. The temperature coefficient is specified at 138 PPM/°C.

Feature Summary

• Provides adjustable precision voltage reference functionality in a compact surface-mount package
• Designed for low-voltage applications with extended industrial temperature operation capabilities
• Offers high initial accuracy for stable reference performance across operating conditions

Applications

• Low-voltage precision power supply regulation
• Industrial control systems requiring wide temperature stability
• Battery-powered equipment needing accurate voltage monitoring

Procurement Notes

Verify the complete part number including the G4 suffix to ensure compliance with RoHS directives and lead-free manufacturing standards. Confirm that the SOT-23-3 package matches your PCB footprint requirements. Check for any specific tape and reel specifications if automated assembly is planned. Ensure the supplier provides valid traceability documentation for quality assurance purposes.

Selection Notes

Select this component when low-voltage precision regulation is required alongside extended temperature tolerance. The 0.5% initial accuracy suits applications demanding tight voltage tolerances. Compare against standard TL432 variants if automotive or harsh environment qualification is necessary. Consider the 80 mA current capability for load driving needs within the low-voltage domain.

Part Context

This part belongs to the TLVH432 family of low-voltage adjustable shunt regulators. It shares functional similarities with the TL432 series but is optimized for lower input voltage ranges and wider operating temperatures. The G4 suffix indicates a green/RoHS-compliant variant manufactured by Texas Instruments.

Replacement Considerations

TLVH432BCDBZR is the non-RoHS compliant equivalent. TLVH432BQDBZR is the qualified automotive-grade alternative.
