Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix 'G' indicates RoHS compliance as per manufacturer documentation. Confirm the USP-6C package dimensions match your PCB footprint requirements. Ensure input voltage sources remain within the 650 mV to 5.5 V operational window to maintain stable regulation. Check for any specific handling precautions related to the small form factor during assembly.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a fixed 3.3 V output is required from variable or low-voltage inputs. It is suitable for applications prioritizing minimal static power consumption over high current delivery. Consider the USP-6C package constraints for layout density. Evaluate thermal performance if operating near the upper temperature limits.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the XC9145 series of boost converters designed for ultra-low power applications. The series includes variants with different fixed output voltages, such as the XC9145B36CER-G which provides 3.6 V. All members share similar architectural features including low quiescent current and compact packaging options.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

The XC9145B36CER-G is a direct pin-compatible alternative within the same series, offering a 3.6 V output instead of 3.3 V. Verify that the system load can tolerate the higher voltage level before substituting.
