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 supply. For an 8 V output the input must be at least Vout + Vd (Vd ~ 2 V typ.), and absolute-max is 35 V (DC). Should be bypassed with a 0.33 uF ceramic close to the pin. |+| 2 | GND | power_in | Common ground reference for both input and output. Internally tied to the DPAK exposed tab, which also serves as the thermal path (RthJC = 8 degC/W). |+| 3 | OUTPUT | power_out | Regulated +8 V output. Delivers up to 500 mA with internal current limit (Isc ~ 300 mA at Vi = 35 V, Iscp ~ 700 mA peak). A 0.1 uF ceramic to GND at the pin is recommended for stability. |+| TAB | GND(TAB) | power_in | DPAK exposed metal tab. Internally connected to pin 2 (GND) and used as the primary heat-sinking surface; solder to a copper pour for thermal dissipation. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | STMicroelectronics |+| Package | TO-252-2(DPAK) |+| Category | PMIC |+| Pins | 4 |++## Ordering variants++- `L78M08CDT-TRCDT-TR`+- `L78M08CDT-TRCDT`+- `L78M08CDT-TRCV`+- `L78M08CDT-TRACV`+- `L78M08CDT-TRABV`+- `L78M08CDT-TRCP`+- `L78M08CDT-TRACP`+- `L78M08CDT-TRCH`++## CAD (KiCad official)++- Symbol: `L78M08CDT-TR`+- 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:** [STMicroelectronics datasheet](https://www.st.com/resource/en/datasheet/l78m08cdt-tr.pdf) (47 pp, sha256 `7cee4c5f6a43332c`, retrieved 2026-08-17, tier: manufacturer)+- **Extractor:** `ds2sf` (Claude).
