Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix 'UMP182X' against the official datasheet to confirm the exact output voltage tolerance and thermal grade. Ensure that the WLCSP-6 package compatibility matches your PCB layout requirements. Confirm end-of-life status if long-term supply continuity is required for production.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a fixed 1.82 V rail is necessary for logic or memory interfaces. The 600 mA current rating suits low-power microcontrollers. Consider the 6 MHz frequency for smaller inductor selection compared to lower-frequency alternatives. Verify input voltage stability within the 2.3 V to 5.5 V window for proper operation.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the FAN5361 series of TinyBuck regulators. It shares architectural similarities with other models in the family, such as the FAN5361UC12X, but differs in output voltage configuration. The series is characterized by its small form factor and integrated synchronous switches, targeting portable applications where board space is limited.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

Direct substitutes include other FAN5361 variants with different output voltages, such as FAN5361UC182X, provided the voltage requirement changes. Cross-model replacement requires verifying pinout compatibility and current ratings. No direct equivalent from other manufacturers is confirmed in public documentation.
