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 | Ground / common reference pin. Common return for input and output; for a negative regulator this pin is the most-positive terminal. |+| 2 | IN | power_in | Unregulated negative input voltage. Absolute max Vi = -35 V; typical operating range -14.5 V to -27 V. Bypass with a 0.33 uF capacitor (Ci) close to the pin. |+| 3 | OUT | power_out | Regulated -12 V output (typ). Delivers up to 100 mA (IOM 0.1 A). Bypass with a 0.1 uF capacitor (Co) close to the pin for optimum stability and transient response. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | TWGMC |+| Package | SOT-89 |+| Category | PMIC |+| Pins | 3 |++## CAD (KiCad official)++- Symbol: `79L12`+- Footprint: `Package_TO_SOT_SMD:SOT-89-3`+- 3D model: SOT-89 (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [TWGMC datasheet](docs/79l12-datasheet.pdf) (2 pp, sha256 `c1a0d6c49d6d3487`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
