IRU1050-33CD

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

The IRU1050-33CD is a low dropout (LDO) linear voltage regulator manufactured by Infineon Technologies, formerly International Rectifier. It provides a fixed 3.3V output with a minimum continuous output current capability of 5A. The device operates within an ambient temperature range of 0°C to +150°C and is housed in a DPAK (TO-263) surface-mount package.

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

Verify the manufacturer origin, as the part was originally produced by International Rectifier before its acquisition by Infineon. Confirm the specific suffix 'CD' corresponds to the DPAK-5 package variant. Ensure the component meets the required thermal dissipation specifications for the intended 5A load application.

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

Select this component when a stable 3.3V rail is required at currents exceeding standard LDO capabilities. The 5A rating distinguishes it from lower-power regulators. Consider the thermal performance in the DPAK package relative to the PCB copper area available for heat sinking.

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

This regulator belongs to the IRU1050 series of high-current LDOs. The series includes variants with different output voltages and packages. The IRU1050-33CD specifically denotes the 3.3V fixed output version in the DPAK-5 surface-mount configuration, designed for robust power management applications.

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

Check for direct pin-compatible equivalents within the same series or family. Verify that any substitute maintains the 5A current rating and 3.3V output tolerance. Ensure thermal characteristics are comparable to prevent overheating in the target application.
