IRU1010-33CD

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Overview

The IRU1010-33CD is a positive fixed-output linear voltage regulator (LDO) manufactured by Infineon Technologies. It provides a stable 3.3V output with a maximum continuous current capability of 1A. The device features low dropout characteristics, ensuring efficient regulation even with small input-to-output voltage differentials. Integrated protection mechanisms include over-current limiting and thermal shutdown to safeguard the component under fault conditions. It is housed in a DPAK (TO-252-3) surface-mount package, designed for reliable operation in space-constrained applications requiring precise voltage regulation.

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

Verify part authenticity through authorized distributors as this component is listed as obsolete. Confirm that the DPAK package matches your PCB footprint requirements. Check for lead-free compliance status if environmental regulations apply to your assembly process. Ensure adequate thermal management design due to the power dissipation characteristics of linear regulators at 1A loads.

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

Select this component when a fixed 3.3V output is required with moderate current demands up to 1A. Consider the low dropout特性 for applications where input voltage may vary close to the output level. Evaluate thermal performance within the DPAK package for your specific ambient temperature conditions. Compare against switching regulators if efficiency is critical, as LDOs dissipate excess voltage as heat.

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

The IRU1010 series represents Infineon's line of linear voltage regulators designed for general-purpose power management. This specific model belongs to the category of positive fixed-output LDOs. It was originally developed by International Rectifier before being acquired by Infineon Technologies. The product serves as a solution for noise-sensitive analog circuits and digital logic supplies where simple, low-noise regulation is preferred over complex switching topologies.

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

As the IRU1010-33CD is marked obsolete, verify equivalent parts from Infineon or other manufacturers offering 3.3V 1A LDOs in compatible packages. Ensure pinout compatibility and electrical specifications match exactly. Consult official replacement guides from Infineon for validated alternatives.
