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 / common return. Reference for the internal bandgap and feedback divider that sets the 4.3V output. Tab of the SOT-223 is internally tied to GND (pin 1) and should be soldered to a copper pour for heat spreading. |+| 2 | VOUT | power_out | Regulated 4.3V output (±2%). Sources up to 1A continuous with a typical dropout of ~665mV at 400mA and ~1250mV at 800mA. Requires a 10µF ceramic output capacitor (CL) for stability. |+| 3 | VIN | power_in | Unregulated input supply, VOUT+1.3V (dropout headroom) up to 18V absolute max. A 10µF ceramic input capacitor (CIN) is required close to this pin. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | MICRONE |+| Package | SOT-223 |+| Category | PMIC |+| Pins | 3 |++## Ordering variants++- `ME6118A43B3GB3G`+- `ME6118A43B3GM3G`+- `ME6118A43B3GPG`+- `ME6118A43B3GK3G`+- `ME6118A43B3GN8AG`++## CAD (KiCad official)++- Symbol: `ME6118A43B3G`+- Footprint: `Package_TO_SOT_SMD:SOT-223-3_TabPin2`+- 3D model: SOT-223 (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [MICRONE datasheet](docs/me6118a43b3g-datasheet.pdf) (22 pp, sha256 `b356c56c07463946`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
