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 | Input | power_in | Unregulated positive input supply. Must remain approximately 2.0 V above the +12 V output (dropout ~2.0 V typ.) and not exceed 35 Vdc absolute max. A 0.33 uF ceramic input capacitor is required if the device is located an appreciable distance from the supply filter. |+| 2 | Ground | power_in | Device common / ground reference. A common ground is required between the input and output sides of the regulator. On the DPAK-3 (DT SUFFIX, CASE 369C) package the heatsink tab (drawn as terminal 4) is internally connected to pin 2 (Ground). |+| 3 | Output | power_out | Regulated +12 V positive output, capable of delivering >1.0 A with internal short-circuit and thermal protection. An output capacitor (Co) is not strictly required for stability but improves transient response; values <0.1 uF may cause instability. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | onsemi |+| Package | TO-252-2(DPAK) |+| Category | PMIC |+| Pins | 3 |++## Ordering variants++- `MC7812BDTRKGDTRKG`+- `MC7812BDTRKGDTRK`+- `MC7812BDTRKGD2TG`+- `MC7812BDTRKGD2TR4G`+- `MC7812BDTRKGTG`+- `MC7812BDTRKGBTG`++## CAD (KiCad official)++- Symbol: `MC7812BDTRKG`+- Footprint: `Package_TO_SOT_SMD:TO-252-2`+- 3D model: TO-252-2(DPAK) (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [onsemi datasheet](https://www.onsemi.com/pdf/datasheet/mc7812bdtrk-d.pdf) (28 pp, sha256 `a0831a3a6a3010ac`, retrieved 2026-08-17, tier: manufacturer)+- **Extractor:** `ds2sf` (Claude).
