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

Verify the specific suffix '18' confirms the fixed 1.8V output variant, as the base IRU1010 series offers adjustable options. Confirm RoHS compliance status for the specific manufacturing lot, as older stock may differ from current production runs. Ensure the SOT-223 package matches the target PCB footprint requirements before finalizing procurement orders.

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

Select this component when a precise 1.8V rail is required without external feedback resistors. It is suitable for applications where input voltages do not exceed 7V and moderate current up to 1A is sufficient. Consider the thermal performance in the SOT-223 package if operating near maximum current limits or high ambient temperatures.

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

This part belongs to the IRU1010 family of low-dropout linear regulators from Infineon. While the base model supports adjustable outputs, the -18 suffix designates the fixed 1.8V configuration. It serves as a power management integrated circuit (PMIC) component designed for simple, cost-effective voltage regulation in compact electronic designs.
