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 supply input. For the 5-V variant, V_IN must be at least V_OUT + 1.8 V (≈7.2 V min) and no greater than 35 V absolute maximum. A 0.33 µF input bypass capacitor (C_IN) is recommended near the pin. |+| 2 | GND | power_in | Ground / common return for the regulator. On the TO-252 (NDP) package the exposed tab is electrically connected to GND and provides the primary thermal path (R_θJA ≈ 38 °C/W, R_θJC(top) ≈ 48.4 °C/W). |+| 3 | OUTPUT | power_out | Regulated +5 V output, capable of >0.5 A. Output voltage is 4.8-5.2 V at I_L = 500 mA (T_J = 25 °C). A 0.1 µF output capacitor (C_O) is recommended for transient/stability performance. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Texas Instruments |+| Package | TO-252 |+| Category | PMIC |+| Pins | 3 |++## Ordering variants++- `LM78M05CDTXCDT`+- `LM78M05CDTXCDTX`+- `LM78M05CDTXCT`+- `LM78M05CDTXH`++## CAD (KiCad official)++- Symbol: `LM78M05CDTX`+- 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:** [Texas Instruments datasheet](https://www.ti.com/lit/ds/symlink/lm78m05cdtx.pdf) (26 pp, sha256 `bf4bbc5ec1195c41`, retrieved 2026-08-17, tier: manufacturer)+- **Extractor:** `ds2sf` (Claude).
