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. Absolute max 35 V (for Vo = 5-18 V variants). A 0.33 uF input decoupling capacitor to GND is recommended per the application circuit. |+| 2 | GROUND | power_in | Common ground reference and current return. Electrically connected to the DPAK metal tab, which acts as the primary thermal path to the PCB copper. |+| 3 | OUTPUT | power_out | Regulated 5 V positive output, capable of sourcing up to 500 mA with adequate heat sinking. Short-circuit current typically 300 mA. A 0.1 uF output capacitor to GND is recommended for transient response. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | STMicroelectronics |+| Package | TO-252-2(DPAK) |+| Category | PMIC |+| Pins | 3 |++## Ordering variants++- `L78M05ABDT-TRDT`+- `L78M05ABDT-TRDT-TR`+- `L78M05ABDT-TRT`+- `L78M05ABDT-TRP`+- `L78M05ABDT-TRDP`++## CAD (KiCad official)++- Symbol: `L78M05ABDT-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/l78m05abdt-tr.pdf) (45 pp, sha256 `13a3708896033a32`, retrieved 2026-08-17, tier: manufacturer)+- **Extractor:** `ds2sf` (Claude).
