Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix CMR-G against the official datasheet to confirm the SOT-25-5 package and reel packaging quantity. Ensure the fixed 3.4 V output aligns with design requirements, as other variants in the series offer different voltages. Confirm RoHS compliance status through manufacturer documentation prior to integration.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a fixed 3.4 V rail is required from a 2 V to 6 V source. The 600 mA capacity suits moderate load applications. The absence of a shutdown pin distinguishes it from variants with control features. Verify thermal performance in the target enclosure given the small footprint.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the XC9237 series of synchronous step-down converters. It shares core electrical characteristics with siblings like the XC9237A13CMR-G and XC9237A32CMR-G, differing primarily in the fixed output voltage setting. The series targets compact power solutions requiring minimal external components.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

XC9237A32CMR-G offers a similar form factor but outputs 3.2 V. XC9237A13CMR-G provides 1.3 V output. Direct substitution requires verifying that the voltage difference meets system tolerances.
