Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix 'SC3' against the official Texas Instruments datasheet to confirm pinout and functional compatibility. Ensure the order includes the correct tape-and-reel packaging designation. Confirm that the AEC-Q100 grade meets the specific temperature class requirements of the target application before finalizing procurement.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a single-output step-down solution is required for 48V or similar automotive networks. The 1.5 A current rating suits moderate load applications where space is constrained. Consider the 2.1 MHz frequency for minimizing passive component size compared to lower-frequency alternatives. Verify thermal performance within the VQFN-HR-12 package for the expected ambient conditions.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the LMR36015 family of ultra-small synchronous buck converters. It shares the core architecture with other variants in the series but differs in specific suffix designations that may indicate package variations or testing grades. It complements higher-current models like the LMR36015F and lower-current options within the broader Texas Instruments automotive power management portfolio.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

Direct substitutes include other LMR36015 variants such as LMR36015FSCQRNXTQ1, provided the electrical parameters and pin configurations are identical. Cross-reference the specific SC3 suffix details with TI documentation to ensure no functional differences exist before substitution.
