TL432BQDBVRE4

Overview

The TL432BQDBVRE4 is an adjustable precision shunt regulator manufactured by Texas Instruments. It operates within a supply voltage range of 2.5 V to 36 V and provides an output current capability of up to 100 mA. The device features an initial accuracy of ±1% at 25°C and maintains stability across a temperature range of -40°C to +125°C. Packaged in a compact SOT-23-3 surface-mount format, it serves as a high-performance reference for power management applications.

Feature Summary

• Adjustable output voltage set via external resistors
• High thermal stability over extended industrial temperatures
• Compact three-terminal surface-mount package

Applications

• Board-level voltage regulation
• Switching power supply feedback loops
• Portable equipment power management

Procurement Notes

Verify the complete part number including the E4 suffix to ensure lead-free compliance and specific manufacturing lot details. Confirm the package type matches the design footprint requirements. Check for any recent product change notices regarding assembly sites or material composition updates before finalizing procurement plans.

Selection Notes

Select this component when a precise, adjustable voltage reference is required in space-constrained designs. It offers superior thermal performance compared to standard Zener diodes. Ensure the external resistor network supports the desired voltage range within the 36 V maximum limit.

Part Context

This device belongs to the TL432 family, which shares functional similarities with the TL431 but utilizes a different pinout configuration suitable for SOT-23 packages. It is designed to replace discrete Zener diodes in various regulation circuits while providing better accuracy and lower impedance characteristics.

Replacement Considerations

Direct substitutes include TL432BQDBVT and TL432BQDBVR. Verify pin compatibility as the TL432 pinout differs from the TL431 series. Ensure replacement parts meet the same automotive qualification standards if applicable.
