Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix LCPR against the official datasheet to confirm the SOT-89-5 package and fixed 850 mV output configuration. Ensure compatibility with your PCB footprint and thermal requirements. Confirm RoHS compliance status through the manufacturer's documentation before finalizing procurement decisions.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this part when a fixed low-voltage output is required without external resistor programming. The 1.2 MHz frequency allows for smaller passive components compared to lower-frequency alternatives. Consider the SOT-89-5 package size constraints and thermal dissipation capabilities relative to the expected load current and ambient temperature conditions.

Voltage Regulators - DC DC Switching Regulators Part Context

This component belongs to the XC9287 series of HiSAT-COT synchronous buck converters. The series offers various fixed output voltages and packaging options, including USP-C-EP-6 and SOT-89-5. All variants share common electrical characteristics such as 1.5 A output capability and 15 uA quiescent current, differing primarily in output voltage settings and physical package dimensions.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

Check for other XC9287 variants with identical SOT-89-5 packaging and 850 mV output if supply issues arise. Verify that any substitute maintains the same 1.2 MHz switching frequency and HiSAT-COT control architecture to ensure circuit stability and performance parity.
