Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix 'DMR' corresponds to the 3 MHz switching frequency variant, as other suffixes like 'CMR' indicate different frequencies. Confirm the output voltage is 2.5 V, distinct from other XC9141 variants. Ensure the package matches SOT-25-5 requirements for your PCB layout.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this part when a fixed 2.5 V output is required from low-voltage sources. The 3 MHz frequency allows for smaller external components compared to lower-frequency variants. Verify that the 800 mA peak current meets load demands under minimum input voltage conditions.

Voltage Regulators - DC DC Switching Regulators Part Context

This component belongs to the XC9141 family of synchronous boost converters. It shares the SOT-25-5 footprint and basic topology with siblings like XC9141B33DMR-G but differs in output voltage and switching frequency specifications defined by its unique alphanumeric suffix.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

XC9141E25CMR-G offers similar functionality but operates at a 1.2 MHz switching frequency. XC9141B33DMR-G provides a 3.3 V output instead of 2.5 V. Cross-reference datasheets to ensure compatibility with existing circuit designs.
