Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the current lifecycle status before procurement planning. Official documentation indicates this specific part number has reached End-of-Life (EOL) status as of June 30, 2022. Sourcing may require checking for obsolete stock or alternative distributors. Confirm RoHS compliance and material declarations if required for specific manufacturing standards. Lead times are not applicable due to discontinuation.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component only if legacy compatibility is required, as it is discontinued. For new designs, consider modern equivalents from the same manufacturer family that offer updated availability. Ensure the 500mA load requirement fits within the specified limits. Verify that the 3.5V minimum input voltage aligns with the system's power rail characteristics. The small footprint makes it suitable for space-constrained layouts where larger packages are not feasible.

Voltage Regulators - DC DC Switching Regulators Part Context

This device belongs to the FAN5362 series of high-frequency synchronous buck regulators. The series is characterized by its ability to deliver moderate current in very small packages. The UMP33X suffix denotes the specific 3.3V fixed output variant within this lineup. These regulators are typically used in portable electronics and embedded systems requiring efficient voltage step-down.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

Official substitutes should be identified through onsemi's cross-reference tools. Potential alternatives include other members of the FAN5362 family or newer PMIC generations from onsemi. Verify pinout compatibility and electrical specifications when considering replacements.
