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 supply input, VCC. Absolute maximum 30 Vdc (32 V peak transient <300 ms). For 3.3 V output, Vin must be at least VO + dropout (~3.68 V at 100 mA). |+| 2 | Ground | power_in | Device ground and reference return. Electrically common with the DPAK heatsink tab (shown as terminal 4 in the case outline drawing). |+| 3 | Output | power_out | Regulated 3.3 V output, up to 100 mA continuous (typ. current limit 220 mA). Requires ≥1.0 µF output capacitor for loop stability. |+| 4 | Tab/GND | power_in | DPAK exposed metal heatsink tab. Internally bonded to Pin 2 (Ground). Solder to a copper pour to lower junction-to-ambient thermal resistance (RθJA = 92 °C/W with recommended pad, RθJC = 6.0 °C/W). |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | onsemi LP2950CDT 3 3RKG |+| Package | TO-252-2(DPAK) |+| Category | PMIC |+| Pins | 4 |++## Ordering variants++- `LP2950CDT-3.3RKGCDT-3.3`+- `LP2950CDT-3.3RKGCDT-3.3RKG`+- `LP2950CDT-3.3RKGACDT-3.3`+- `LP2950CDT-3.3RKGCZ-3.3`+- `LP2950CDT-3.3RKGACZ-3.3`+- `LP2950CDT-3.3RKGCD-3.3`+- `LP2950CDT-3.3RKGACD-3.3`+- `LP2950CDT-3.3RKGNCV2951ACD-3.3R2`+- `LP2950CDT-3.3RKGCN-3.3`+- `LP2950CDT-3.3RKGACN-3.3`+- `LP2950CDT-3.3RKGCDM-3.3`+- `LP2950CDT-3.3RKGACDM-3.3`++## CAD (KiCad official)++- Symbol: `LP2950CDT-3.3RKG`+- 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:** [onsemi LP2950CDT 3 3RKG datasheet](https://www.onsemi.com/pdf/datasheet/lp2950cdt-3.3rk-d.pdf) (22 pp, sha256 `88c1955e96318431`, retrieved 2026-08-17, tier: manufacturer)+- **Extractor:** `ds2sf` (Claude).
