Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the suffix DDCT indicates cut-tape packaging when ordering. Confirm the X suffix corresponds to the 1.1MHz switching frequency variant. Ensure compatibility with the SOT-23-THIN-6 footprint during PCB layout. Cross-reference the manufacturer datasheet for latest marking and pinout revisions before finalizing procurement specifications.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a 40V input limit and 600mA continuous current are sufficient for the design. The 1.1MHz frequency balances component size and efficiency. Consider thermal performance within the thin package if operating near maximum load. Verify that the required output voltage falls within the 0.765V to 38.4V adjustable range defined by the feedback resistor network.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the LMR14006 family of non-synchronous buck regulators. It shares core architecture with variants like LMR14006YDDCT, which differs primarily in switching frequency. The series targets applications needing simple design with minimal external passive components while maintaining robust protection features against overcurrent and thermal stress.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

LMR14006YDDCT offers identical functionality but operates at a 2.1MHz switching frequency, allowing smaller inductors.
