TL432CDBVRE4

Overview

The TL432CDBVRE4 is an adjustable precision shunt voltage reference manufactured by Texas Instruments. It operates within a cathode voltage range of 2.5 V to 36 V and provides an initial accuracy of 2%. The device features a maximum shunt current of 100 mA and a minimum operating current of 600 µA. It is housed in a SOT-23-5 surface-mount package and supports an extended industrial temperature range from -40°C to +125°C.

Feature Summary

• Adjustable output voltage capability across a wide operational range
• High precision with specified initial accuracy tolerance
• Extended temperature rating suitable for demanding environments

Applications

• Portable equipment power supply regulation
• Battery-powered system voltage monitoring
• General-purpose voltage reference circuits

Procurement Notes

Verify the specific suffix 'E4' indicates RoHS compliance and lead-free construction as per manufacturer documentation. Confirm the package type matches the required PCB footprint. Ensure the ordering quantity aligns with standard reel or cut tape availability constraints defined by the supplier.

Selection Notes

Select this component when a compact, low-cost adjustable reference is required for space-constrained designs. The SOT-23-5 package offers a small form factor compared to larger alternatives. Consider the 2% accuracy specification against circuit requirements before finalizing the design choice.

Part Context

This part belongs to the TL432 family of adjustable shunt regulators. It serves as a drop-in replacement for fixed references in many applications while offering programmable output voltage through external resistors. The E4 suffix typically denotes environmental compliance modifications within the product line.

Replacement Considerations

Direct pin-compatible substitutes include other TL432 variants with matching accuracy and package specifications. Verify thermal performance and electrical characteristics against the original datasheet requirements before substitution.
