Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the manufacturer origin, as Fairchild Semiconductor's power management division is now part of ON Semiconductor. Confirm the specific suffix 'S710X' matches the required tape-and-reel quantity and marking code. Ensure the component meets RoHS compliance standards if required for your assembly process. Cross-reference the datasheet revision date to ensure compatibility with your design specifications.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a fixed 1V output is required without external feedback resistors. It is suitable for applications prioritizing small footprint due to the SC-70-6 package. Consider the 2MHz switching frequency for smaller passive component sizes compared to lower-frequency alternatives. Ensure the load current does not exceed 500mA continuous operation.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the FAN5358 family of synchronous buck converters. These regulators are designed for space-constrained portable applications. The series typically offers high efficiency and low quiescent current. The FAN5358S710X specifically provides a fixed 1V output, distinguishing it from adjustable variants in the same product line.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

Check for direct pin-compatible replacements within the FAN5358 family that offer different output voltages or current ratings. Verify electrical parameters such as switching frequency and thermal performance against potential substitutes. Ensure the alternative component maintains the same SC-70-6 package outline for mechanical compatibility.
