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

Verify the exact part number including suffixes such as 'TR' which indicates tape and reel packaging. Confirm RoHS compliance status if required for your manufacturing process. Ensure the supplier provides genuine Semtech Corporation components to guarantee performance specifications like dropout voltage and PSRR are met. Check datasheet revisions for any updates on electrical characteristics or recommended operating conditions before finalizing procurement.

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

Select this component when a fixed 2.5V output is required with up to 3A current capacity. Consider the TO-263 package for thermal management needs. Evaluate the 1.35V dropout voltage against your input-output differential requirements. The 14mA quiescent current impacts overall system efficiency, particularly in battery-operated devices. Verify that the 72dB PSRR meets noise sensitivity requirements of the downstream circuitry.

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

This part belongs to the EZ1085 series of high-performance positive voltage regulators designed by Semtech Corporation. The series is engineered for applications demanding low dropout performance at currents up to 3A. Variants within the series offer different fixed output voltages, such as 2.5V and 3.3V, while maintaining similar current capabilities and protection features. The TO-263 package is common across the series for standard surface-mount mounting.

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

Direct substitutes within the same family include other EZ1085 variants with different fixed output voltages, such as EZ1085CM-3.3 TR, if the application allows for a change in regulated voltage. Ensure the replacement maintains the 3A current rating and compatible package type. Cross-referencing with other manufacturers' 3A linear regulators requires careful verification of pinout compatibility, dropout voltage characteristics, and protection feature alignment.
