Комментарии об отличиях

MIC29150-ADJ ↔ SGM2122-ADJ

MIC29150-ADJ: Vin(max)=16V, Vout=1.25-15V (adj), Iout=1.5A, dropout=350mV@1.5A, Vref=1.24V, ±1%, Super Beta PNP. SGM2122-ADJ: pin-to-pin. Формула Vout=1.24*(1+R2/R1) — проверить Vref SGM2122 (может 1.25V). R1=120Ω typical. Dropout 350mV@1.5A — excellent для high-current applications: 3.3V из 3.7V Li-Ion возможно при Iout<1A. Enable pin (5-pin version MIC29152): logic ON/OFF + error flag — SGM2122 verify. Reverse battery: -20V protection встроено. Output capacitor: ceramic/tantalum — не чувствителен к ESR. Ground pin current: 20-30mA — higher than CMOS, обусловлено PNP base drive. PSRR: ~65dB@120Hz, ~45dB@10kHz. Thermal: при Vin=5V→Vout=3.3V@1.5A Pd=2.55W — SOT-223 с large copper pour допустим; при Vin=12V→3.3V Pd=13W — только TO-220 или buck pre-reg.
