Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix /V+ indicates lead-free compliance and RoHS status. Confirm the package type matches the 16-TSSOP-EP specification. Check current availability as distribution may vary by region. Ensure the fixed 5 V output aligns with target load requirements before ordering.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a fixed 5 V rail is required from a 3.5 V to 28 V source. The 1 A output current capability suits moderate load applications. The 2.1 MHz frequency allows for smaller external passive components compared to lower-frequency alternatives. Verify thermal performance within the -40°C to +125°C operating range.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the MAX16903 family of mini-buck converters. The 'S' designation typically denotes automotive-grade qualification. The 'UE50' suffix specifies the 5 V fixed output voltage. The '/V+' suffix indicates RoHS-compliant packaging. This series targets compact power solutions in constrained spaces.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

Check for MAX16903RAUE50/V+T if tape-and-reel packaging is preferred over tubes. Verify pinout compatibility with existing layouts. Consider MAX16909R if higher current or adjustable output is needed.
