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

This component is officially marked as obsolete and no longer manufactured by Infineon Technologies. Procurement should focus on verifying the authenticity of existing stock from authorized distributors or secondary market suppliers. Buyers must confirm the specific revision status and ensure compliance with any applicable tariff regulations when shipping to restricted regions. Due to its discontinued status, long-term availability cannot be guaranteed.

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

Designers requiring this specific 3.3V fixed output should consider that the IRU1010-33CP is obsolete. Selection should prioritize compatible replacement regulators with similar electrical characteristics, such as 1A output current and low dropout performance. Verify that alternative components offer comparable package dimensions if board space is constrained. Ensure the new selection supports the required 7V maximum input voltage range.

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

The IRU1010 series belongs to Infineon's lineup of low dropout (LDO) linear regulators. The -33 suffix indicates a fixed 3.3V output configuration. The CP suffix typically denotes the package type and temperature grade. As part of the International Rectifier portfolio acquired by Infineon, these devices were designed for efficient power management in portable and embedded electronics before being phased out.

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

Public confirmed substitute part numbers are not available in the provided documentation. Designers should consult Infineon's official obsolescence notices or distributor cross-reference tools for equivalent modern LDO regulators with matching 3.3V output and 1A current ratings.
