Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the suffix 'NOPB' confirms lead-free and RoHS compliance as per manufacturer specifications. Ensure the package designation 'XMXA' matches the required PowerTSSOP footprint for PCB layout compatibility. Cross-reference the specific revision level in the latest datasheet to confirm pinout consistency before finalizing procurement orders.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a fixed 0.8V output is required without external feedback resistors. It is suitable for applications needing compact solutions due to the integrated switch and high-frequency operation. Consider the 2A current limit and input voltage constraints against the system's power budget and thermal requirements.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the LM2852 series of synchronous buck regulators. It shares the core topology with variants offering different fixed output voltages, such as 1.5V, 1.8V, and 3.3V. The XMXA package provides a compact surface-mount solution suitable for space-constrained designs.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

Direct substitutes include other LM2852 variants with different fixed outputs (e.g., LM2852XMXA-1.8/NOPB) if voltage adjustment is possible via external components, though the internal reference differs. Verify equivalent current ratings and package dimensions for mechanical fit.
