Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix DMR-G against the official datasheet to confirm the SOT-25-5 package and reel packaging configuration. Ensure the fixed 1.8 V output rating matches the design requirements. Cross-reference the manufacturer part number directly with Torex Semiconductor documentation to avoid substitution errors with similar series variants.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a fixed 1.8 V output is required from a variable or low-input source up to 6 V. The 3 MHz switching frequency allows for smaller external passive components compared to lower-frequency alternatives. Verify that the 500 mA load current does not exceed the thermal limits of the SOT-25-5 package under expected ambient conditions.
