TL432BIDBVR

Overview

The TL432BIDBVR is an adjustable precision shunt regulator manufactured by Texas Instruments. It operates within a supply voltage range of 2.495 V to 36 V and features an initial accuracy of 0.5%. The device supports a maximum shunt current of 100 mA with a maximum reference input voltage of 37 V. It utilizes a SOT-23-5 surface-mount package and functions across a temperature range from 0°C to +70°C. The unit weighs approximately 6.3 mg.

Feature Summary

• Provides adjustable output voltage via external resistors
• Offers high precision with 0.5% initial accuracy
• Features low output impedance for stable regulation

Applications

• Board-level regulators
• Adjustable power supplies
• Switching power supplies

Procurement Notes

Verify the specific suffix 'G4' for lead-free compliance if required, as datasheets may list TL432BCDBVRG4. Confirm the commercial temperature grade (0°C to +70°C) matches system requirements. Check RoHS status details on the manufacturer's official documentation. Ensure the SOT-23-5 footprint aligns with PCB design constraints before ordering.

Selection Notes

Select this component when precise voltage referencing is needed in space-constrained designs. The SOT-23-5 package offers a compact solution compared to larger alternatives. Consider the 0.5% accuracy for applications requiring tighter tolerance than standard 1% or 2% variants. Verify that the 100 mA current capability meets load requirements.

Part Context

This part belongs to the TL432 family of adjustable precision shunt regulators. It shares functional similarities with the TL431 but differs in pinout configuration for DBV, DBZ, and PK packages. The TL432 series is designed to replace Zener diodes in various regulation applications while offering superior stability and adjustability.
