Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the exact output current rating (500 mA vs 800 mA) against the official datasheet, as sources vary. Confirm the SOT-25-5 package type and RoHS compliance status. Ensure the fixed 2.5 V output matches system requirements. Check for any specific ordering suffixes or variants that may affect electrical characteristics or packaging.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a fixed 2.5 V output is required from a low-voltage source up to 6 V. The 3 MHz switching frequency allows for smaller inductors and capacitors compared to lower-frequency alternatives. Consider the 800 mA peak capability for transient loads, while adhering to thermal constraints in the SOT-25-5 package.
