Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the manufacturer designation as National Semiconductor or Texas Instruments on official datasheets. Confirm the suffix NOPB indicates lead-free compliance. Ensure the package type matches the required 8-WFBGA footprint. Cross-reference the specific revision level if critical for legacy system compatibility. Always consult the latest electrical characteristics table before finalizing design integration.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a compact, high-efficiency buck converter is needed for low-current applications. The 2MHz switching frequency allows for smaller inductors compared to lower-frequency alternatives. Ensure the input voltage remains above 2.7V and the required output does not exceed 3.16V. Consider thermal performance within the WFBGA package for the expected ambient temperature range of -30°C to 85°C.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the LM3202 family of synchronous buck regulators. It shares functional similarities with other members like the LM3203 but differs in specific electrical parameters and pin configurations. The transition from National Semiconductor to Texas Instruments means documentation may reference either entity, though the hardware specifications remain consistent for this specific part number.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

Check for LM3202TLX/NOPB as a potential variant with identical electrical specifications but potentially different tape-and-reel packaging. Verify pin-to-pin compatibility if substituting with other synchronous buck regulators from the same family.
