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 DC input. Recommended input capacitor Ci = 0.33 uF near the pin. Absolute-maximum V_I = 35 V (for V_O = 5..18 V variants). Typical operating input for 78M08 is Vi = 14 V (range 10.5..25 V). |+| 2 | GND | power_in | Common ground reference for input and output. On TO-252 and SOT-223 the exposed metal tab is electrically tied to GND and provides the primary thermal path (theta_JC = 12.5 C/W TO-252, 15 C/W SOT-223). |+| 3 | OUTPUT | power_out | Regulated +8 V output (7.68..8.32 V at 25 C, I_O = 350 mA). Sourcing up to 1 A DC (typ. short-circuit current 800 mA, peak current 1300 mA). Recommended output capacitor Co = 0.1 uF near the pin for stability. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | UMW |+| Package | TO-252 |+| Category | PMIC |+| Pins | 3 |++## CAD (KiCad official)++- Symbol: `78M08`+- 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:** [UMW datasheet](docs/78m08-datasheet.pdf) (16 pp, sha256 `162df1416fa16ead`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
