Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm the specific suffix indicates the 1.05V fixed output variant. Check for End-of-Life status updates as availability may be restricted. Ensure compliance with RoHS standards and verify packaging options such as cut tape or reel availability for production integration.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a fixed 1.05V rail is required in space-constrained designs. The 6 MHz frequency allows for smaller passive components compared to lower-frequency alternatives. Consider the 600mA limit against peak load requirements. The WLCSP-6 package suits applications where board area is limited. Verify input voltage stability within the 2.5V to 5.5V range.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the FAN53601 series of synchronous buck regulators. It shares the same form factor and switching frequency with other variants in the family but differs in fixed output voltage settings. The series targets mobile and portable applications requiring efficient power management in minimal footprints.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

Direct substitutes include other FAN53601 variants with different fixed output voltages if the voltage requirement changes. Cross-reference pinout compatibility before substitution. Verify thermal performance and current ratings match application needs.
