Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the complete part number including the suffix to confirm the specific output voltage variant. Ensure the ordering code matches the required switching frequency configuration if not internally fixed. Confirm package availability and lead times through authorized distributors as stock levels fluctuate.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a stable 0.8V rail is required from a 3.3V or 5V source. The choice between 500kHz and 1500kHz depends on available board space for passive components versus noise sensitivity requirements. Verify that the external inductor and capacitor values align with the chosen switching frequency for optimal stability.

Voltage Regulators - DC DC Switching Regulators Part Context

This regulator belongs to the LM2852 series, designed for compact DC-DC conversion solutions. It replaces older linear regulators in applications where heat dissipation is a constraint. The SIMPLE SWITCHER architecture simplifies design by integrating the controller and power switches into a single monolithic IC.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

LM2852XMXAX-0.8/NOPB may be substituted with other LM2852 variants offering different fixed outputs, provided the system voltage requirements change accordingly. Cross-referencing pinouts and thermal characteristics is essential when moving between different output voltage versions within the same family.
