Комментарии об отличиях

LP38692-3.3 ↔ SGM2202-3.3V

LP38692-3.3: Vin=2.7-10V, Vout=3.3V, Iout=1A, dropout=450mV@1A, ±2.5%, ceramic stable, Iq=55uA, ENABLE pin (active high/low — проверить polarity!). SGM2202-3.3V: pin-to-pin. ENABLE pin позволяет shutdown в 1uA off-state — critical для battery-powered с power sequencing. Проверить: (1) Enable threshold — LP38692 typ 0.9V-2.0V; SGM2202 — verify. (2) Enable pull-up/pull-down — internal? LP38692 может требовать external pull-up. (3) Off-state current: 1uA typ — verify SGM2202. Output capacitor: ceramic 1uF min. PSRR: ~60-70dB@1kHz. Min Vin=3.75V@1A. Для MCU power sequencing: Enable подключить к 3.3V MCU GPIO (2.5-3.3V logic compatible).
