Комментарии об отличиях

MIC29150-3.3 ↔ SGM2122-3.3V

MIC29150-3.3: Vin(max)=16V (20V abs max), Vout=3.3V, Iout=1.5A, dropout=350mV@1.5A (typ), ±1% accuracy, Super Beta PNP process, reverse battery protection. SGM2122-3.3V: pin-to-pin, Iout=1.5A. Dropout: MIC29150 350mV@1.5A vs SGM2122 проверить (возможно 400-500mV). Min Vin: 3.3+0.35=3.65V — можно питать от Li-Ion 3.7V! Ground pin current: MIC29150 ~20-30mA@1.5A (PNP pass element) — выше чем CMOS; SGM2122 — verify. PSRR: Super Beta PNP даёт ~60-65dB@120Hz; SGM2122 — verify. Output capacitor: MIC29150 stable с ceramic и tantalum (не чувствителен к ESR); SGM2122 — verify ceramic stability. Accuracy ±1% — adequate. Reverse battery protection: MIC29150 встроен; SGM2122 — проверить, возможно требует external diode. Thermal: Pd=(5-3.3)*1.5=2.55W, SOT-223 θJA~62°C/W → ΔT=158°C — требуется copper pour >2sq.inch или DPAK.
