Voltage Regulators - DC DC Switching Regulators Procurement Notes
Verify the complete part number including suffixes against official Texas Instruments documentation to ensure correct pinout and thermal characteristics. Confirm automotive grade compliance (AEC-Q100) if required by your specific application standards. Check moisture sensitivity levels and recommended reflow profiles prior to assembly to prevent package damage during manufacturing.
Voltage Regulators - DC DC Switching Regulators Selection Notes
Select this component when an 80V input tolerance is necessary without external protection circuits. The fixed 5V output simplifies design for standard logic loads. Consider the WSON-12 package for space-constrained PCB layouts. Ensure the load current does not exceed 1.5A continuous operation limits under maximum ambient temperature conditions.
Voltage Regulators - DC DC Switching Regulators Part Context
This part belongs to the LMR380xx-Q1 family of SIMPLE SWITCHER converters. It shares architectural similarities with other members like the LMR38025 and LMR38010 but differs in output current capability and fixed voltage settings. The 'FS' suffix typically denotes specific thermal or packaging variations within the automotive portfolio.
Voltage Regulators - DC DC Switching Regulators Replacement Considerations
Direct substitutes include LMR38015S5QDRRQ1 for non-reel variants or LMR38025S5QDRRRQ1 if higher current is acceptable. Verify pin compatibility before swapping. Generic equivalents may lack automotive qualification.
