Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the complete part number including suffixes such as /NOPB against official Texas Instruments documentation to ensure correct RoHS compliance and specific tape-and-reel or cut-tape packaging options. Confirm that the SOT-23-5 footprint matches your PCB layout requirements before finalizing procurement orders.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when input voltages are limited to 5.5 V and moderate output currents around 1.5 A are required. The fixed 1.6 MHz frequency is suitable for space-constrained designs where smaller inductors are preferred over lower-frequency alternatives. Ensure thermal management accounts for the small SOT-23-5 package size under full load conditions.

Voltage Regulators - DC DC Switching Regulators Part Context

This device belongs to the LMR10515 family of Simple Switcher regulators. It shares core topology and performance characteristics with variants like the LMR10515XMFX/NOPB and LMR10515XSD/NOPB, differing primarily in packaging styles such as SOT-23-5 versus WSON-6 while maintaining identical electrical specifications.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

Direct substitutes include LMR10515XMFX/NOPB and LMR10515XMFENOPB which share the same electrical profile. Verify pinout compatibility and thermal dissipation capabilities when swapping between different package types within the same series.
