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

Verify the specific suffix CS for the 8-SOIC package configuration. Confirm RoHS compliance status as datasheets may vary by production batch. Check for end-of-life notices or obsolescence warnings from Infineon before finalizing procurement plans.

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

Select this component when a fixed 3.3V rail is required with 1A capacity. Ensure the input voltage does not exceed 12V. Verify that the 8-SOIC footprint fits the PCB layout. Consider thermal dissipation requirements given the 0.65V dropout at 1A load.

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

This part belongs to the IRU series of linear regulators from Infineon. It serves as a fixed-output variant within the broader PMIC portfolio, designed for simple, cost-effective voltage regulation tasks where high efficiency is less critical than simplicity and low noise performance.

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

Check for direct pin-compatible replacements if sourcing is difficult. Verify that any substitute maintains the 3.3V fixed output and 1A current rating. Ensure the replacement package matches the 8-SOIC form factor.
