TL432BCPK

Overview

The TL432BCPK is an adjustable precision shunt voltage reference manufactured by Texas Instruments. It operates within a supply voltage range of up to 36 V and provides an adjustable output voltage from 2.495 V to 36 V. The device features an initial accuracy of ±0.5% and a temperature coefficient of 92 PPM/°C. It supports a maximum cathode current of 100 mA with a minimum operating current of 600 µA. The component functions reliably across an extended temperature range from -40°C to +125°C. It is housed in a surface-mount SOT-89-3 package.

Feature Summary

• Provides stable adjustable reference voltage with high initial accuracy
• Operates over a wide temperature range for industrial applications
• Supports high cathode current capability for robust regulation

Applications

• Precision power supply regulation circuits
• Portable equipment voltage monitoring
• Battery-powered system references

Procurement Notes

Verify the specific suffix BCPK to confirm the SOT-89-3 package type and B grade accuracy. Confirm RoHS compliance status through official documentation. Check for moisture sensitivity level requirements during storage and handling. Ensure the supplier provides valid traceability data for quality assurance purposes.

Selection Notes

Select this component when a compact SOT-89-3 footprint is required alongside high accuracy specifications. Consider the 92 PPM/°C temperature coefficient for thermal stability needs. Evaluate the 100 mA current limit against load requirements. Compare against other series members if different package options are preferred.

Part Context

This part belongs to the TL432B series of adjustable shunt regulators. It shares functional similarities with the TL431 family but utilizes a three-terminal configuration suitable for space-constrained designs. The device integrates a bandgap reference and error amplifier on a single monolithic IC structure.

Replacement Considerations

TL432BCPWR offers identical electrical characteristics in a TSSOP-8 package.
