Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the manufacturer designation as Texas Instruments, which acquired National Semiconductor. Confirm the specific suffix /NOPB indicates lead-free and RoHS compliance. Ensure the package type matches the required 10-pin WSON footprint for PCB layout compatibility.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a fixed 1.5V rail is required from a single-cell lithium battery or similar low-voltage source. The 2MHz frequency allows for smaller external passive components compared to lower-frequency alternatives. Verify that the load current does not exceed the 1.5A limit under all operating conditions.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the LM3676 family of simple switchers designed for space-constrained applications. It replaces older linear regulators by offering higher efficiency during step-down conversion. The device is suitable for systems requiring stable voltage regulation from fluctuating battery sources.
