TLVH432BIDBZT

Overview

The TLVH432BIDBZT is an adjustable precision shunt regulator manufactured by Texas Instruments, designed for low-voltage applications. It operates within a cathode voltage range of 2.5 V to 18 V and provides an initial accuracy of ±0.5%. The device supports a maximum cathode current of 80 mA and features a temperature coefficient of 138 ppm/°C. It functions reliably across an operating temperature range of -40°C to +125°C. Packaged in a compact SOT-23-3 surface-mount case, it serves as a high-performance reference solution for space-constrained designs.

Feature Summary

• Adjustable output voltage capability spanning from 2.5 V up to 18 V
• High initial accuracy of ±0.5% ensures precise voltage referencing
• Extended industrial temperature operation ranging from -40°C to +125°C

Applications

• Low-voltage battery-powered equipment requiring stable references
• Portable consumer electronics with strict space limitations
• Industrial control systems needing wide temperature stability

Procurement Notes

Verify the specific suffix 'DBZT' corresponds to the SOT-23-3 package and tape-and-reel quantity configuration. Confirm RoHS compliance status matches REACH requirements for your region. Ensure the ordering part number aligns with the required initial accuracy grade of ±0.5% and the specified 18 V maximum operating voltage limit.

Selection Notes

Select this component when a low-voltage adjustable reference is required alongside high accuracy and extended temperature performance. Compare against standard TL432 variants if higher input voltage tolerance or different packaging options are needed. Consider the 80 mA cathode current limit for load driving capabilities and verify thermal management needs for the SOT-23-3 footprint.

Part Context

This device belongs to the TLVH432 family of low-voltage precision shunt regulators from Texas Instruments. It complements other series like the TL432 and TLVH431, offering specialized performance for sub-20 V applications. The family shares common architectural features but varies in voltage ranges, accuracy grades, and package types to suit diverse design constraints.

Replacement Considerations

TLVH432BCDBZR: Offers similar functionality but with commercial temperature range (0°C to 70°C). TLVH432QDBZT: Provides automotive qualification with 1.5% accuracy. TL432BIDBZT: Supports higher voltages up to 36 V but lacks the low-voltage optimization.
