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 | VOUT | power_out | Regulated +18 V output, up to 150 mA. A 0.1 uF ceramic capacitor to GND improves transient response but is not required for stability. |+| 2 | GND | power_in | Common ground reference. Must be shared between input and output. Quiescent current of ~3-5.5 mA flows out of this pin. |+| 3 | VIN | power_in | Unregulated input supply, typically at least VOUT + 2.0 V (dropout), maximum 30 V. Bypass with 0.33 uF close to the pin for stable operation. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Shikues |+| Package | SOT-89-3 |+| Category | PMIC |+| Pins | 3 |++## CAD (KiCad official)++- Symbol: `78L18`+- Footprint: `Package_TO_SOT_SMD:SOT-89-3`+- 3D model: SOT-89-3 (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [Shikues datasheet](docs/78l18-datasheet.pdf) (7 pp, sha256 `2f2bf1f5a553c543`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
