Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix 'X' indicates reel packaging when ordering. Confirm that the NOPB designation ensures compliance with lead-free environmental standards. Ensure the selected variant matches the required thermal performance for the intended operating environment. Cross-reference the datasheet for exact electrical tolerances before finalizing the bill of materials.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this model when board space is limited and a fixed high switching frequency is preferred over adjustable options. Compare against the LM2735YMFX/NOPB if a lower 520 kHz frequency is acceptable for reduced EMI. Ensure the input source can sustain the required current without dropping below the 2.7 V minimum threshold during peak load conditions.

Voltage Regulators - DC DC Switching Regulators Part Context

This component belongs to the LM2735 series of switching regulators, which are optimized for space-constrained applications. The series offers various package options including WSON and SOT-23 variants. The LM2735XMFX/NOPB specifically utilizes the SOT-23-5 footprint, balancing performance with minimal PCB area consumption compared to larger industrial packages.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

LM2735YMFX/NOPB: Offers identical topology but operates at a fixed 520 kHz frequency instead of 1.6 MHz. LM2735XSDX/NOPB: Provides the same 1.6 MHz performance but utilizes a WSON-6 package rather than SOT-23-5. Verify pinout compatibility and thermal dissipation requirements when substituting.
