TL432IDBVRE4

Overview

The TL432IDBVRE4 is an adjustable precision shunt regulator 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 supports a maximum cathode current of 100 mA with a minimum operating current of 80 µA. It features a temperature coefficient of 92 ppm/°C and functions reliably across an extended temperature range from -40°C to +125°C. Packaged in a compact SOT-23-5 surface-mount format, it serves as a stable voltage reference for power management applications.

Feature Summary

• Provides adjustable precision voltage regulation via external resistor divider
• Operates over an extended industrial temperature range up to 125°C
• Supports high cathode current capability for robust load driving

Applications

• Precision voltage references in power supply circuits
• Voltage monitoring and threshold detection systems
• Battery-powered equipment requiring stable reference voltages

Procurement Notes

Verify the complete part number including the E4 suffix to confirm lead-free compliance and specific manufacturing lot details. Confirm the package type matches the design requirements, as variations exist between SOT-23-3 and SOT-23-5 configurations within the broader family. Ensure compatibility with RoHS directives if required by the target market regulations.

Selection Notes

Select this component when an adjustable shunt regulator is needed with ±2% initial accuracy and operation up to 36 V. It is suitable for designs requiring extended temperature performance up to 125°C. Compare against fixed-reference alternatives if precise output adjustment is not necessary. Consider the SOT-23-5 footprint constraints during PCB layout planning.

Part Context

This device belongs to the TL432 series of adjustable precision shunt regulators from Texas Instruments. It shares functional similarities with the TL431 but offers specific packaging and electrical characteristics tailored for modern surface-mount applications. The E4 suffix indicates lead-free construction compliant with international environmental standards.

Replacement Considerations

Direct replacements include the TL432IDBVR and TL432IDBZT. Verify pinout compatibility and thermal performance when substituting.
