IRU1010-33CS

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

The IRU1010-33CS is a positive fixed linear voltage regulator IC manufactured by Infineon Technologies. It provides a stable 3.3V output with a maximum current capacity of 1A. The device features a maximum dropout voltage of 1.3V at full load and offers a power supply rejection ratio (PSRR) of 70dB at 120Hz. It includes over-current and over-temperature protection mechanisms to ensure reliable operation within an operating temperature range of 0°C to 150°C. The component is housed in an 8-SOIC package.

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

Verify the specific suffix CS indicates the 8-SOIC package configuration and fixed 3.3V output. Confirm RoHS compliance status as some variants may differ. Check for end-of-life notices or discontinuation dates from official Infineon channels before finalizing procurement plans to ensure long-term availability.

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

Select this component when a fixed 3.3V output is required without external feedback resistors. Ensure input voltage exceeds 3.3V plus the 1.3V dropout margin. Verify thermal management requirements for 1A loads in SOIC packages. Compare PSRR specifications against noise-sensitive application needs.

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

This part belongs to the IRU1010 family of low dropout linear regulators from Infineon Technologies, formerly International Rectifier. The family includes adjustable and fixed voltage variants. The IRU1010-33CS specifically denotes the fixed 3.3V version in surface-mount packaging, designed for compact power management solutions.

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

Official substitutes include IRU1010-33CSPBF for lead-free compliance. Cross-reference pinouts and thermal characteristics carefully. Verify that alternative LDOs match the 1A current rating and 3.3V fixed output requirement.
