Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix 'CMR' against official datasheets to confirm the 1.2 MHz switching frequency variant. Ensure the ordering code matches the required 5.3 V fixed output specification. Confirm RoHS compliance status and packaging options directly with authorized distributors prior to purchase.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a stable 5.3 V rail is required from single-cell lithium sources. The 800 mA capacity suits moderate load applications. Consider the 1.2 MHz frequency for balancing component size and efficiency. Verify thermal performance requirements for the SOT-25-5 package under expected load conditions.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the XC9141 series of synchronous boost converters. It shares the core topology with variants offering different output voltages or switching frequencies. The 'C' designation typically indicates the specific switching frequency characteristic within the product family.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

XC9141B50CMR-G offers a similar form factor but provides a fixed 5 V output instead of 5.3 V. XC9141B33CMR-G provides a 3.3 V output option. Verify that the voltage difference does not impact downstream circuit operation before substituting.
