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 supply input. Recommended operating input voltage up to 32 V (absolute max 36 V). Bypass to GND with a 0.33 µF ceramic capacitor close to the pin for stability. |+| 2 | GND | power_in | Device ground / common reference for both input and output. On TO-220 the tab is electrically connected to this pin. |+| 3 | OUTPUT | power_out | Regulated +12 V output (11.75-12.25 V typ at TJ=25°C, IOUT up to 1 A). Requires a 0.1 µF output capacitor to GND for transient response; internally current-limited and protected by thermal shutdown and safe-area protection. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Diodes Incorporated |+| Package | TO-220 |+| Category | Power Management (PMIC) |+| Pins | 3 |++## Ordering variants++Same part, different packaging or reel option.++- `AS7812AT-E1`+- `AS7812AT-E1ADTR-G1`++## CAD (KiCad official)++- Symbol: `AS7812AT-E1`+- Footprint: `Package_TO_SOT_THT:TO-220-3_Vertical`+- 3D model: TO-220 (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [Diodes Incorporated datasheet](https://jlcpcb.com/api/file/downloadByFileSystemAccessId/8560094637638369280) (19 pp, sha256 `a3112666d50a186d`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
