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 | Input supply voltage. Recommended operating range 2.5V to 6.0V (absolute max 6.5V). Bypass with a 1.0µF ceramic capacitor (X5R/X7R) to GND close to the pin. |+| 2 | GND | power_in | Device ground reference for the internal reference, error amplifier, and pass FET return current. |+| 3 | EN | input | Chip enable input. Drive high (VIH ≥ 1.5V, up to 6.0V) for normal operation; drive low (VIL ≤ 0.4V) to shut down the regulator. Internal ~3MΩ pull-down to GND; when EN is low, VOUT is discharged through an internal ~60Ω resistor. |+| 4 | NC | unconnected | No internal connection. Leave floating or tie to GND per board practice. |+| 5 | VOUT | power_out | Regulated 1.2V output (±1.5% accuracy) capable of 600mA (min). Requires a 1.0µF ceramic/tantalum/aluminum electrolytic capacitor to GND for stability. Foldback short-circuit protection limits current to ~50mA into a shorted output. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Diodes Incorporated AP2112K 1 2TRG1 |+| Package | SOT-25 |+| Category | PMIC |+| Pins | 5 |++## Ordering variants++- `AP2112K-1.2TRG1`+- `AP2112K-1.2TRG1K-1.8TRG1`+- `AP2112K-1.2TRG1K-2.5TRG1`+- `AP2112K-1.2TRG1K-2.6TRG1`+- `AP2112K-1.2TRG1K-3.3TRG1`+- `AP2112K-1.2TRG1R5-1.2TRG1`+- `AP2112K-1.2TRG1R5-1.8TRG1`+- `AP2112K-1.2TRG1R5-2.5TRG1`+- `AP2112K-1.2TRG1R5-2.6TRG1`+- `AP2112K-1.2TRG1R5-3.3TRG1`+- `AP2112K-1.2TRG1R5A-1.2TRG1`+- `AP2112K-1.2TRG1R5A-1.8TRG1`+- `AP2112K-1.2TRG1R5A-2.5TRG1`+- `AP2112K-1.2TRG1R5A-2.6TRG1`+- `AP2112K-1.2TRG1R5A-3.3TRG1`+- `AP2112K-1.2TRG1M-1.2TRG1`+- `AP2112K-1.2TRG1M-1.8TRG1`+- `AP2112K-1.2TRG1M-2.5TRG1`+- `AP2112K-1.2TRG1M-2.6TRG1`+- `AP2112K-1.2TRG1M-3.3TRG1`++## CAD (KiCad official)++- Symbol: `AP2112K-1.2TRG1`+- Footprint: `Package_TO_SOT_SMD:SOT-23-5`+- 3D model: SOT-25 (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [Diodes Incorporated AP2112K 1 2TRG1 datasheet](https://www.diodes.com/assets/Datasheets/AP2112K-1.2TRG1.pdf) (None pp, sha256 `ef8d376f2ec356e2`, retrieved 2026-08-17, tier: manufacturer)+- **Extractor:** `ds2sf` (Claude).
