Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.++## Pinout++| Pin | Name | Type | Function |+|---|---|---|---|+| 1 | GND | power_in | Device ground reference. Must be tied solidly to system ground; per the datasheet's PCB layout note, incomplete grounding lets the internal zero-potential shift with switching current and destabilizes operation. |+| 2 | LX | power_out | Switching node (energy-conversion pin). Connects to the external boost inductor (typ. 22 µH) whose other terminal ties to VIN. Absolute max on LX is -0.3 to 6 V; ILXmax rated 1000 mA (current limit typ. 1000 mA, min 800 mA). |+| 3 | VOUT | power_out | Regulated boost output, fixed 5.0 V (±2%) for the A50 option code. Requires an external output capacitor (recommended 47 µF or larger, low-ESR tantalum preferred; 100 µF used in the typical application). Absolute max -0.3 to 6 V; rated 300 mA. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | MICRONE |+| Package | SOT-23 |+| Category | PMIC |+| Pins | 3 |++## Ordering variants++- `ME2188A50M3GM3`+- `ME2188A50M3GX`+- `ME2188A50M3GM5`+- `ME2188A50M3GP`+- `ME2188A50M3GT`++## CAD (KiCad official)++- Symbol: `ME2188A50M3G`+- Footprint: `Package_TO_SOT_SMD:SOT-23`+- 3D model: SOT-23 (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [MICRONE datasheet](docs/me2188a50m3g-datasheet.pdf) (11 pp, sha256 `197aa5944f496234`, retrieved 2026-08-17, tier: lcsc)+- **Datasheet language:** Chinese.
