The non-synchronous topology means you need an external Schottky catch diode — the inductor current freewheels through that diode, not an internal FET. ## SOT-23-5 — what the package tells the rework bench Housed in a SOT-23-5 (SC-74A) package, the part sits on a 5-pin footprint with 0.95 mm pitch. That pitch is wide enough for a standard fine-tip iron or hot-air pencil — no micro-BGA rework station needed.","metaTitle":"Texas Instruments LMR10510YMF/NOPB SIMPLE SWITCHER, 1A Buck","metaDescription":"Texas Instruments LMR10510YMF/NOPB SIMPLE SWITCHER step-down regulator, 3-5.5V input, 1A output, 3MHz switching, SOT-23-5.
