Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix 'C0' against the official datasheet to confirm the fixed 3.6V output voltage, as suffixes define the output setting. Ensure the WLP-5-03 package type matches your PCB footprint requirements. Confirm RoHS compliance status directly with the manufacturer documentation before finalizing procurement specifications.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a fixed 3.6V output is required from a 2V to 6V input source. The 600mA current capability suits moderate load applications. Consider the 1.2MHz frequency for balancing component size and efficiency. Verify that the WLP-5-03 package is compatible with your assembly process compared to alternative SOT packages in the same series.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the XC9237 series of synchronous step-down converters manufactured by Torex Semiconductor. The series is characterized by built-in driver transistors and low quiescent currents. The XC9237B3EC0R-G specifically denotes the variant with a fixed 3.6V output and WLP-5-03 packaging, distinguishing it from other output voltages and package types like SOT-25 available in the lineup.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

XC9237B3EC0R-G is the exact equivalent. Other XC9237 variants with different output voltages (e.g., XC9237B33C0R-G for 3.3V) share the same package but differ electrically. Cross-package replacements require verifying pinout compatibility between WLP-5-03 and SOT-25 footprints.
