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 supply input. Recommended operating range 4.3V (VOUT+1V) to 13.2V for the 3.3V version; absolute maximum 15V. Bypass with a 1.0µF ceramic capacitor (CIN) to GND close to the pin. |+| 2 | GND | power_in | Device ground return. Carries the ground-pin quiescent current (typ. 100µA at IOUT=100µA, up to ~4mA at IOUT=300mA). Connect to the system ground plane. |+| 3 | EN | input | Enable input, CMOS/TTL compatible. Logic high (VEN ≥ 2.0V) enables the regulator; logic low (VEN ≤ 0.4V) puts the device in shutdown (ISTD ≤ 1µA). Absolute maximum VEN = 15V; recommended 0 to 13.2V. May be tied to VIN for always-on operation. |+| 4 | BYP | passive | Bypass capacitor pin for low-noise operation on the fixed-output (3.3V) version. Connect a small ceramic capacitor (typ. 100pF, CBYP) from BYP to GND to filter the internal bandgap reference and reduce output noise. On the ADJ variant this same pin is repurposed as the ADJ feedback input. |+| 5 | VOUT | power_out | Regulated 3.3V output, up to 300mA. Accuracy ±1% (typ), ±2% over full temperature. Requires a 2.2µF ceramic output capacitor (COUT) to GND for stability. Internally current-limited (~450mA typ) and thermally protected. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Diodes |+| Package | SOT-23-5 |+| Category | PMIC |+| Pins | 5 |++## Ordering variants++- `AP2210K-3.3TRG1K-3.3TRG1`+- `AP2210K-3.3TRG1K`+- `AP2210K-3.3TRG1N`++## CAD (KiCad official)++- Symbol: `AP2210K-3.3TRG1`+- 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:** [Diodes datasheet](https://www.diodes.com/assets/Datasheets/AP2210K-3.3TRG1.pdf) (30 pp, sha256 `8d83ef61593fff5e`, retrieved 2026-08-17, tier: manufacturer)+- **Extractor:** `ds2sf` (Claude).
