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 compliance. Ensure the package type matches the required 6-WFBGA/DSBGA footprint for PCB layout compatibility.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a fixed 1.82 V output is required without external resistor programming. The 6 MHz switching frequency allows for smaller passive components compared to lower frequency converters. Ensure the load current does not exceed the 600 mA limit and the input voltage remains within the specified 2.3 V to 5.5 V range.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the LM8801 family of high precision synchronous step-down converters. The family includes variants with different fixed output voltages, such as 1.2 V, 2.9 V, and 12 V. The LM8801 series is designed specifically for mobile applications where space and power efficiency are critical constraints.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

Other LM8801 variants with different output voltages (e.g., LM8801TMX-1.2/NOPB) share the same package and functionality but provide different fixed outputs. Direct substitution requires matching the required output voltage specification.
