Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix 'X' indicates the tape-and-reel packaging configuration distinct from cut-tape variants. Confirm RoHS compliance status as the base part number may have non-compliant historical revisions. Ensure the ordering part number matches the required package type and environmental specifications for the target application assembly process.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a compact solution is required for 3V to 5.5V input systems needing up to 1.5A output. The 1.6 MHz frequency allows for smaller inductors compared to lower-frequency alternatives. Consider thermal performance in dense layouts due to the small SOT-23-5 footprint and high current capability.
