Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix 'X' against the manufacturer's official documentation to confirm tape-and-reel packaging specifications. Confirm RoHS compliance status directly through the latest datasheet or environmental declaration, as regulatory status may vary by production batch. Ensure the procurement channel sources units from authorized distributors to guarantee authenticity and traceability, particularly given the component's surface-mount nature.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this regulator when a fixed 3.3 V output is required with moderate current demands up to 500 mA. The 3 MHz frequency allows for smaller passive components compared to lower-frequency alternatives. Evaluate thermal performance based on the WLCSP-6 package size and expected ambient conditions. Consider the 55 uA quiescent current impact on overall system efficiency during sleep modes relative to other TinyBuck series options.
