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

Verify the specific suffix 'CY' against the manufacturer's official datasheet to confirm package type and tape/reel specifications. Ensure the component matches the required thermal performance and pinout configuration for your PCB layout. Cross-reference the part number with Infineon's current product status to confirm availability and compliance with relevant environmental standards before finalizing procurement.

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

Select this component when a reliable, low-noise linear regulator is needed for analog or sensitive digital loads. The 800mA output capacity suits moderate power requirements where switching noise must be minimized. Consider the thermal dissipation capabilities of the SOT-223 package relative to the expected load current and ambient temperature conditions during system design.

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

This part belongs to the IRU1117 family of low dropout regulators from Infineon (formerly International Rectifier). The family includes variants with fixed outputs like 1.8V and adjustable versions. The IRU1117CY specifically denotes the adjustable version in an SOT-223 package, distinguishing it from other pinouts or fixed voltage options within the same functional series.
