Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the manufacturer origin, as Texas Instruments acquired National Semiconductor's PMIC business. Confirm the specific suffix 'NOPB' indicates lead-free and RoHS compliance. Ensure the package type matches the required 14-HTSSOP footprint. Check for active status availability through authorized distributors.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a fixed 0.8V output is required for low-voltage logic loads. Consider the 2A current capability against peak load demands. Evaluate the need for 500kHz versus 1500kHz switching based on external inductor size constraints and EMI requirements. Ensure input voltage remains above 2.85V for proper operation.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the LM2852 family of SIMPLE SWITCHER regulators. Other variants in the series offer different fixed output voltages such as 1.0V, 2.5V, and 3.3V. The family shares common features including synchronous operation and adjustable switching frequencies, allowing designers to choose the appropriate voltage level while maintaining consistent performance characteristics.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

Direct substitutes include other LM2852 variants with different fixed outputs like LM2852XMXA-1.0/NOPB or LM2852XMXA-2.5/NOPB if voltage adjustment is possible. Verify pin compatibility and thermal performance before substitution.
