Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the exact part number XC9288B17DPR-G against official Torex Semiconductor documentation to ensure compatibility with your design requirements. Confirm that the fixed 1.75 V output voltage meets your system specifications, as this variant is not adjustable. Check RoHS compliance status through the manufacturer's datasheet or authorized distributor channels before finalizing procurement decisions.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a fixed 1.75 V output is required within a 2.5 V to 5.5 V input range. Consider the 1.5 A current capability and 1.2 MHz switching frequency for applications prioritizing compact passive component sizes. Ensure the SOT-89-5 package fits your PCB layout constraints and thermal management strategy.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the XC9288 series of HiSAT-COT synchronous buck converters. It shares common features like 1.5 A output current and 1.2 MHz frequency with other variants in the series but differs in its fixed output voltage setting of 1.75 V.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations
