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 | Supply input. Recommended operating range 2.2 V to 16 V (absolute max 16 V). A ≥1 µF input capacitor is recommended. |+| 2 | GND | power_in | Device ground reference. Ground pin current is typically 200 µA at 25 mA load and 600 µA at 100 mA load. |+| 3 | ON/OFF | input | Active-low shutdown control input. Drive high (>1.6 V) to enable the regulator; drive low (<0.15 V) to shut down (IQ ≈ 0.01 µA). Must be actively terminated; tie to VIN if unused. Absolute max 16 V. |+| 4 | NC | unconnected | No connect. Leave floating or tie to ground; no internal connection. |+| 5 | VOUT | power_out | Regulated 5.0-V output, 100 mA continuous (short-circuit protected, ~150 mA current limit). Requires a 4.7 µF output capacitor for stability. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Texas Instruments |+| Package | SOT-23-5 |+| Category | PMIC |+| Pins | 5 |++## Ordering variants++- `LP2981A-50DBVRDBVR`+- `LP2981A-50DBVRDBVT`++## CAD (KiCad official)++- Symbol: `LP2981A-50DBVR`+- Footprint: `Package_TO_SOT_SMD:SOT-23-5`+- 3D model: SOT-23-5 (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [Texas Instruments datasheet](docs/lp2981a-50dbvr-datasheet.pdf) (23 pp, sha256 `ad245dedca86e10b`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
