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 DC input supply. Operating range 2.5 V to 16 V; absolute max -0.3 to 16 V. Bypass with a 1 µF input capacitor close to the pin. |+| 2 | GND | power_in | Device ground reference for both the input supply and the regulated output. |+| 3 | INHIBIT | input | TTL-compatible ON/OFF control input. Drive high (VIH >= 1.6 V) to enable the regulator; drive low (VIL <= 0.18 V) to shut it down (<1 µA off-mode current). Not internally pulled-up and must not be left floating; absolute max -0.3 to 16 V. |+| 4 | NC | unconnected | No internal connection. Leave floating or tie to a convenient net; not required for device operation. |+| 5 | VOUT | power_out | Regulated 3.3 V output (LD2980ABM33: 3.284-3.317 V typ. at 1 mA). Guaranteed output current up to 50 mA with internal current and thermal limiting. Requires a 2.2 µF low-ESR ceramic output capacitor for stability. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | STMicroelectronics |+| Package | SOT-23-5L |+| Category | PMIC |+| Pins | 5 |++## Ordering variants++- `LD2980ABM33TRABM33TR`+- `LD2980ABM33TRCM33TR`+- `LD2980ABM33TRABM30TR`+- `LD2980ABM33TRCM18TR`+- `LD2980ABM33TRCM30TR`+- `LD2980ABM33TRABM50TR`+- `LD2980ABM33TRCM50TR`++## CAD (KiCad official)++- Symbol: `LD2980ABM33TR`+- Footprint: `Package_TO_SOT_SMD:SOT-23-5`+- 3D model: SOT-23-5L (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [STMicroelectronics datasheet](https://www.st.com/resource/en/datasheet/ld2980abm33tr.pdf) (22 pp, sha256 `38bf5b337c2cb448`, retrieved 2026-08-17, tier: manufacturer)+- **Extractor:** `ds2sf` (Claude).
