Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix (DMR) against the manufacturer's official datasheet to confirm the exact package type and tape-and-reel specifications. Ensure that the fixed 3.6V output aligns with the target circuit design requirements before procurement. Cross-reference the RoHS compliance status and lead time directly with authorized distributors to avoid counterfeit components.

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. It is suitable for applications prioritizing high efficiency at moderate loads up to 600mA. Consider the SOT-25-5 package constraints for PCB layout. Compare against adjustable variants if flexible output voltages are needed instead of fixed options.
