TLVH432BCDBZTG4

Overview

The TLVH432BCDBZTG4 is a low-voltage adjustable precision shunt regulator manufactured by Texas Instruments. It operates within an output voltage range of 1.24 V to 18 V and features an initial accuracy of ±0.5%. The device supports a maximum cathode current of 70 mA and maintains a typical temperature coefficient of 138 ppm/°C. Designed for surface-mount applications, it utilizes a SOT-23-3 package. The component functions as a shunt reference with a minimum operating current of 100 µA.

Feature Summary

• Provides adjustable precision voltage regulation suitable for low-voltage circuitry
• Delivers high initial accuracy for stable reference performance
• Operates effectively across extended industrial temperature ranges

Applications

• Battery-powered equipment requiring precise voltage references
• Microcontroller supply monitoring circuits
• Portable instrumentation systems

Procurement Notes

Verify the specific suffix 'G4' indicates lead-free compliance and RoHS standards during procurement. Confirm that the 'B' designation aligns with the required ±0.5% accuracy tolerance for your design. Ensure the SOT-23-3 package dimensions match your PCB footprint constraints. Cross-reference the manufacturer datasheet for any recent product change notifications affecting this specific part number.

Selection Notes

Select this component when a low-voltage adjustable reference is required in a compact surface-mount package. It is appropriate for designs needing ±0.5% initial accuracy without demanding ultra-low temperature coefficients. Consider the 70 mA cathode current limit when sizing external components. This part serves as a direct replacement for standard TLVH432 variants with automotive or extended grade qualifications if specified.

Part Context

This device belongs to the TLVH432 family of low-voltage shunt regulators from Texas Instruments. It shares architectural similarities with the TLVH431 but offers higher voltage capability up to 18 V. The 'B' suffix denotes the accuracy grade, while 'G4' signifies environmental compliance. It complements other TI voltage references like the TL431 series but targets lower voltage applications.

Replacement Considerations

The TLVH432BCDBZR is a compatible alternative within the same family offering identical electrical characteristics. Verify package compatibility when substituting with non-TI equivalents such as those from Diodes Incorporated.
