TL432BCDBZT

Overview

The TL432BCDBZT is an adjustable precision shunt regulator manufactured by Texas Instruments. It operates within a voltage range of 2.495 V to 36 V and features an initial accuracy of ±0.5%. The device supports a maximum cathode current of 100 mA and withstands input voltages up to 37 V. It is housed in a SOT-23-3 surface-mount package and functions across a temperature range of -40 °C to +85 °C.

Feature Summary

• Provides stable reference voltage with high initial accuracy
• Adjustable output capability for flexible circuit design
• Compact surface-mount packaging for space-constrained applications

Applications

• Precision voltage reference circuits
• Power supply regulation systems
• Battery-powered equipment monitoring

Procurement Notes

Verify the specific suffix 'B' indicates the commercial temperature grade (-40°C to +85°C) and ±0.5% accuracy, distinct from other variants like 'I' or 'C'. Confirm RoHS compliance status and moisture sensitivity level (MSL 1) prior to assembly. Ensure ordering documentation matches the exact part number to avoid substitution errors with similar TL432 series components.

Selection Notes

Select this component when precise voltage referencing is required in compact designs. The SOT-23-3 package suits limited board space. Consider the ±0.5% tolerance for critical accuracy needs. Evaluate thermal performance within the specified operating range. Compare against higher accuracy industrial grades if extended temperature stability is essential for the target application environment.

Part Context

This device belongs to the TL432 family of adjustable precision shunt regulators from Texas Instruments. It shares architectural similarities with the TL431 but offers enhanced performance characteristics. The product line utilizes internal bandgap references to maintain stability. It serves as a fundamental building block for power management integrated circuits requiring reliable voltage control.
