Procurement Notes

Verify the specific suffix codes against official Texas Instruments documentation to confirm package type and accuracy grade. Ensure compatibility with existing PCB footprints for the SOT-23-3 configuration. Cross-reference RoHS compliance status with current regulatory requirements before finalizing procurement decisions for production runs.

Selection Notes

Select this component when designing circuits that require a low-voltage, high-accuracy shunt regulator in a small form factor. Consider the 70 mA cathode current limit for load driving capabilities. Evaluate the thermal performance within the specified -40°C to +125°C range to ensure reliability under varying environmental conditions during operation.

Part Context

This part belongs to the TLVH432 series of low-voltage adjustable precision shunt regulators from Texas Instruments. It serves as a cost-effective alternative to traditional Zener diodes, offering superior stability and lower temperature coefficients. The series is widely used in power management integrated circuits where space-saving surface-mount packages are required for modern electronic designs.

Replacement Considerations

Direct substitutes include other TLVH432 variants with different accuracy grades or packaging options, such as TLVH432AIDBZR or TLVH432BCDBZR. Verify pinout compatibility and electrical specifications before substitution to maintain circuit integrity.
