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 +12 V output. Typical 12 V (11.4-12.6 V) at Io up to 100 mA. Recommended output bypass capacitor Cout = 0.1 uF to ground. |+| 2 | GND | power_in | Common ground reference for the regulator. On SOT-89 this pin is also the tab/heat-spreader and should be connected to the ground plane for thermal dissipation. |+| 3 | IN | power_in | Unregulated input voltage. Absolute maximum Vi = 35 V; typical operating range approximately 14 V to 27 V for 12 V output. Recommended input bypass capacitor Cin = 0.33 uF to ground. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Foshan Blue Rocket Elec |+| Package | SOT-89-3 |+| Category | PMIC |+| Pins | 3 |++## Ordering variants++- `78L12TT`++## CAD (KiCad official)++- Symbol: `78L12T`+- 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:** [Foshan Blue Rocket Elec datasheet](docs/78l12t-datasheet.pdf) (None pp, sha256 `4aad7919c9a0e03d`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
