Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix (e.g., NOPB) as it denotes lead-free status and may affect availability. Confirm the exact output voltage variant, as the base model number often corresponds to a family with multiple fixed voltage options. Check for obsolete status or last-time-buy notices from the manufacturer before finalizing procurement plans.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a fixed 1.5 V output is required from a single-cell lithium-ion or similar 3 V to 5.5 V source. Ensure the application demands up to 3 A continuous current. Consider the 14-pin HTSSOP footprint for PCB layout compatibility. Verify that the 550 kHz switching frequency aligns with electromagnetic interference constraints and inductor size requirements.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the LM2853 series of synchronous buck regulators. The series offers various fixed output voltages determined by internal EEPROM settings. The MH suffix indicates the 14-pin HTSSOP package type. The device integrates power switches and control logic into a single compact solution for space-constrained designs.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

The LM2853MHX-1.5/NOPB is a verified equivalent variant with identical electrical specifications and pinout. Other members of the LM2853 family with different fixed output voltages share the same package but provide different voltage levels.
