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 | VIN | power_in | Unregulated supply voltage input. Absolute max 40V; typical operating range 7-20V for 78M05. A 0.22μF (0.33μF per electrical characteristics) ceramic bypass capacitor to GND is required close to the pin for stability. |+| 2 | GND | power_in | Common ground reference for input and output. Tied internally to the exposed tab/cooling rib of the package. |+| 3 | OUTPUT | power_out | Regulated +5V output (4.9V min / 5.1V max for 78M05), up to 700mA with adequate heat sinking. A 1μF output capacitor to GND is recommended for load-transient response. |+| TAB | GND | power_in | Exposed metal tab / cooling rib, internally connected to GND (pin 2). Solder to a copper pour on the PCB for thermal dissipation (TO-252-2L max power dissipation ~2W at Tc=25°C). |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | XBLW L78M05HDTR XBLW |+| Package | TO-252 |+| Category | PMIC |+| Pins | 4 |++## Ordering variants++- `L78M05HDTRHDTR`+- `L78M05HDTRSDTR`+- `L78M05HDTRCV`++## CAD (KiCad official)++- Symbol: `L78M05HDTR`+- 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:** [XBLW L78M05HDTR XBLW datasheet](docs/l78m05hdtr-datasheet.pdf) (12 pp, sha256 `1cf9b83662066f88`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
