Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the suffix 'Q' indicates AEC-Q100 automotive qualification and 'AX' denotes the specific tape-and-reel packaging configuration. Confirm the manufacturer part number matches Texas Instruments documentation exactly. Ensure compatibility with required operating temperatures and voltage levels before procurement. Cross-reference datasheet revisions to confirm pinout and electrical characteristics remain unchanged.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a single-output synchronous buck converter with automotive qualification is required. It is suitable for designs needing up to 1.5 A output current with input voltages up to 38 V. Consider the 16-HTSSOP package constraints for thermal management and PCB layout. Compare against non-automotive variants if cost sensitivity outweighs qualification requirements.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the LM26001 family of synchronous buck regulators from Texas Instruments. It shares core topology with standard versions but includes automotive-grade screening and qualification. The 'Q' prefix distinguishes it as an automotive-qualified device, while the base model number indicates its functional class within the broader PMIC portfolio.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

LM26001MXAX/NOPB is a non-automotive equivalent with identical electrical specifications but lacks AEC-Q100 qualification.
