• Voltage reference for ADC/DAC circuits

Procurement Notes

Verify the specific suffix 'G4' indicates lead-free and RoHS compliance status as per manufacturer documentation. Confirm the tape and reel packaging format matches production requirements. Ensure the ordering part number aligns exactly with the required temperature grade and package variant to avoid substitution errors during assembly.

Selection Notes

Select this component when a compact, low-cost shunt regulator with precise reference voltage is needed. Consider the SOT-23 footprint constraints and thermal performance relative to load currents. Evaluate the dynamic impedance characteristics against noise sensitivity requirements in the target circuit design.

Part Context

This part belongs to the TLVH432 family of adjustable shunt regulators. It serves as a cost-effective alternative to discrete Zener diodes or more complex IC references. The family is designed for applications requiring stable voltage references in space-constrained environments.

Replacement Considerations

Check for direct pin-compatible alternatives such as other TLVH432 variants with different suffixes. Verify if generic shunt regulators meet the specific accuracy and temperature range requirements before substituting.
