Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix #PBF indicates lead-free compliance and RoHS adherence before procurement. Confirm the MSOP-8 package dimensions match your PCB footprint requirements. Ensure the supply chain source provides valid manufacturer traceability documentation. Check for any recent Product Change Notifications (PCN) regarding material or manufacturing site updates that may affect long-term availability or specifications.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a compact solution is required for converting 3.7V lithium-ion battery voltages to lower logic levels. The 1.4 MHz frequency allows for smaller external inductors and capacitors compared to lower-frequency alternatives. Consider the thermal performance of the MSOP package under maximum load conditions. Verify that the required output voltage falls within the 800 mV to 6 V adjustable range defined by the feedback resistor network.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the LTC3404 series of monolithic switching regulators designed for space-constrained applications. It is distinct from higher-current variants like the LTC3414 or different topology converters in the Analog Devices portfolio. The EMS8 suffix specifically denotes the MSOP-8 package style, differentiating it from tape-and-reel versions such as the TRPBF variant.
