Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix 'ED' confirms the 1.45V output voltage, as variations exist within the XC9287 series. Confirm RoHS compliance status through official documentation. Ensure the SOT-89-5 package matches your PCB footprint requirements. Check for any regional distribution restrictions or limited availability notices before finalizing procurement plans.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a fixed 1.45V output is required from a 2.5V to 5.5V input source. The 1.5A output capability suits moderate load applications. Consider the 1.2MHz switching frequency for balancing size and noise. Verify that the -40°C to +105°C operating range meets environmental constraints. Compare against other XC9287 variants if different output voltages are needed.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the XC9287 series of synchronous step-down DC/DC converters. The series features HiSAT-COT technology, allowing for small external component counts. Torex Semiconductor designs these ICs for high efficiency and stability in space-constrained portable electronics. The XC9287 family offers various output voltage options within the same package type.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

Other XC9287 variants with different output voltage suffixes may serve as functional replacements if the voltage requirement changes. Direct substitutes must maintain the 1.5A current rating and SOT-89-5 package. Verify pin compatibility and thermal performance before swapping.
