Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix 'DMR' confirms the SOT-25-5 package and 3MHz oscillator setting against the official datasheet. Confirm RoHS compliance status and check for any lead-free soldering requirements during assembly. Ensure the ordering quantity matches the manufacturer's standard packaging specifications to avoid handling discrepancies.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this model when a fixed 1.8V output is required from a 2V to 6V input source. The 3MHz frequency allows for smaller inductors compared to 1.2MHz variants. Verify that the load current does not exceed 600mA and that the application environment stays within the specified operating temperature range for optimal performance.

Voltage Regulators - DC DC Switching Regulators Part Context

This component belongs to the XC9235 series of synchronous rectification type DC/DC converters. The series is characterized by high efficiency and low quiescent current, making it suitable for portable applications. The 'A' designation indicates a minimum input voltage of 2.0V, while the 'D' suffix typically denotes the USP-C-EP-6 package; however, the 'DMR' suffix specifically identifies the SOT-25-5 variant with a 3MHz oscillator.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

Cross-reference with other XC9235 variants such as XC9235A3KCMR-G for identical electrical performance but different packaging. Ensure substitute parts maintain the same 3MHz switching frequency and 1.8V fixed output voltage to guarantee compatibility with existing PCB layouts and thermal designs.
