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 | OUT | power_out | Regulated positive output, nominal +9 V (8.64 - 9.36 V at Tj = 25 °C). Deliverable output current up to ~100 mA. A 0.1 µF ceramic output capacitor to GND is recommended for stability. |+| 2 | GND | power_in | Common ground / reference return for both the input and output sides of the regulator. |+| 3 | IN | power_in | Unregulated positive input supply. Absolute max 35 V; typical operating range 11.4 V - 24 V for a regulated 9 V output. A 0.33 µF input capacitor to GND is recommended when the regulator is located far from the bulk supply filter. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Unknown |+| Package | SOT-89 |+| Category | PMIC |+| Pins | 3 |++## CAD (KiCad official)++- Symbol: `78L09`+- 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:** [Unknown datasheet](docs/78l09-datasheet.pdf) (2 pp, sha256 `cc83a993874b173a`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
