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 | GND | power_in | Ground reference for the regulator. Tie directly to the system ground plane; quiescent current (~25µA) returns through this pin. |+| 2 | VOUT | power_out | Regulated 3.3V output (±2% accuracy). Sources up to 150mA continuous (250mA current-limited). Requires a ≥1µF ceramic output capacitor with ESR between 0.01Ω and 100Ω for stability. |+| 3 | VIN | power_in | Unregulated input voltage supply, 2V to 6V recommended operating range (6.5V absolute max). Requires a 1µF ceramic input capacitor. For 3.3V output, VIN should be ≥ 3.5V to stay out of dropout at rated load. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Diodes |+| Package | SOT-23 |+| Category | PMIC |+| Pins | 3 |++## Ordering variants++- `AP2120N-3.3TRG1TRG1`+- `AP2120N-3.3TRG1N-3.3TRG1`++## CAD (KiCad official)++- Symbol: `AP2120N-3.3TRG1`+- Footprint: `Package_TO_SOT_SMD:SOT-23`+- 3D model: SOT-23 (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [Diodes datasheet](https://www.diodes.com/assets/Datasheets/AP2120N-3.3TRG1.pdf) (19 pp, sha256 `66be4c8fbb47afd5`, retrieved 2026-08-17, tier: manufacturer)+- **Extractor:** `ds2sf` (Claude).
