Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix ADJ-TR confirms the adjustable output variant and tape-and-reel packaging format. Ensure compatibility with the 6-UTDFN footprint dimensions during PCB layout. Confirm RoHS compliance status if required for specific regulatory environments. Cross-reference the manufacturer part number against official distributor catalogs to validate current production status and availability channels.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a compact solution is required for stepping down voltages between 2.7V and 5.5V to lower levels up to 600mA. The 1.6MHz frequency allows for smaller inductors and capacitors compared to lower-frequency alternatives. Consider the thermal requirements of the 6-UTDFN package and ensure adequate copper area on the PCB for heat dissipation given the exposed pad configuration.
