Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix 'MXA' against the manufacturer's latest datasheet to confirm pinout and thermal pad configurations, as variations exist within the LM26001 family. Ensure the ordering part number matches the required package style and RoHS compliance status documented in official TI release notes before finalizing procurement.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when designing systems requiring a wide input voltage range up to 38V and moderate output currents around 1.5A. It is suitable for applications prioritizing efficiency at light loads due to its sleep mode feature. Designers should verify that the desired output voltage falls within the 1.234V to 35V range and that the operating temperature requirements align with the specified -40°C to 125°C junction limit.

Voltage Regulators - DC DC Switching Regulators Part Context

This device belongs to the LM26001 series of non-synchronous buck regulators from Texas Instruments. It shares architectural similarities with other members like the LM26003 but differs in output current capacity and package options. The series is designed for general-purpose DC/DC conversion where efficiency and simple implementation are key requirements.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

Direct substitutes include LM26001MX/NOPB (standard PowerTSSOP) and LM26001MXAX/NOPB (extended temperature variant). For higher current needs, consider the LM26003MH/NOPB. Verify pin compatibility and thermal performance when transitioning between these variants.
