Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Procurement Notes

Verify the specific suffix CD against official Infineon documentation to confirm package type and packaging method. Ensure compatibility with the required 1.8V fixed output specification. Cross-reference the part number with authorized distributors to confirm availability and authenticity before procurement.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Selection Notes

Select this component when a stable 1.8V rail is required for low-voltage integrated circuits. The 800mA current rating supports moderate load requirements. Consider the Ultra Thin-PAK package for space-constrained designs requiring surface-mount integration.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Part Context

This regulator belongs to the IRU1117 series, which includes adjustable variants like the IRU1117. While the standard IRU1117 offers adjustable output for applications such as VGA and sound cards, the -18 variant is specifically optimized for fixed 1.8V generation in PC clock supplies and general low-voltage logic.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Replacement Considerations

Consult official Infineon resources for confirmed substitute part numbers. Generic LDO replacements may not match the specific current capabilities or package dimensions.
