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 | IN | power_in | Unregulated positive supply input. Accepts up to 35V absolute maximum; a 0.33μF ceramic bypass capacitor to GND is recommended close to the pin for stability. |+| 2 | GND | power_in | Ground/common reference for both input and output. Also connected to the exposed tab of the TO-252 package for thermal dissipation. |+| 3 | OUT | power_out | Regulated +9V output, capable of up to 0.5A (typ. 350mA test condition). Requires a 0.1μF ceramic bypass capacitor to GND for transient response; typical short-circuit current is 50mA. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | PJSEMI |+| Package | TO-252 |+| Category | PMIC |+| Pins | 3 |++## Ordering variants++Same part, different packaging or reel option.++- `PJ78M09TE`++## CAD (KiCad official)++- Symbol: `PJ78M09TE`+- Footprint: `Package_TO_SOT_SMD:TO-252-2`+- 3D model: TO-252 (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [PJSEMI datasheet](docs/pj78m09te-datasheet.pdf) (4 pp, sha256 `ddc34df32e6db9d8`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
