Buck or LDO: Choosing a Power Topology
Two numbers decide it: voltage difference times current. Below 1 W an LDO is simpler and quieter; above it the heat has nowhere to go.

Supply boundary
Product records help identify a manufacturer part number and technical family. A listed part may be fulfilled from Chip-seek warehouse-held stock or a reviewed sourcing channel. Source, quantity, packaging, date code, MOQ, price and lead time are confirmed before an order is accepted.

A 10 uF capacitor is not 10 uF at voltage, and above self-resonance it is an inductor. Dielectric, DC bias, SRF and the millimetres that matter.
