Комментарии об отличиях

LP38690-5.0 ↔ SGM2201-5.0V

LP38690-5.0: Vin=2.7-10V, Vout=5.0V, Iout=1A, dropout=450mV@1A (5Vout typ), ±2.5%, ceramic stable, Iq=55uA. SGM2201-5.0V: pin-to-pin. Min Vin = 5.0+0.45 = 5.45V@1A. Для 6V input — margin=550mV, допустимо. Для 5.5V input — max Iout ~300mA (dropout снижается с током). Iq=55uA — невероятно низкий для 1A LDO (vs 5mA у 1117), ideal для battery-powered. Output capacitor: ceramic 1uF min (LP38690 stable with ceramic, НЕ требует ESR) — проверить SGM2201. PSRR: ~60-65dB@1kHz, ~40dB@100kHz — adequate для post-buck filtering. Line regulation: 0.1%/V, load regulation: 0.5% — typical CMOS LDO. Thermal: Pd=(6-5)*1=1W, SOT-223 ΔT~62°C → max Ta=63°C при 1sq.inch copper.
