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 input voltage. Operating range VOUT+0.5V to 6V; absolute maximum 6.5V. Bypass with 1µF ceramic to GND close to the pin. |+| 2 | GND | power_in | Device ground reference for the internal reference, error amplifier, and output feedback divider. |+| 3 | CE | input | Active-high chip-enable input. Logic high (>=1.5V) enables the regulator; logic low (<=0.4V) shuts it down (ISTD ~0.01µA typ). Allowed range -0.3V to VIN+0.3V; do not leave floating. |+| 4 | NC | unconnected | No internal connection. Leave floating or tie to GND as convenient for layout. |+| 5 | VOUT | power_out | Regulated 2.8V output, 300mA (min). Stable with low-ESR ceramic capacitors; 1µF COUT recommended. Short-circuit current-limited (~50mA at VOUT=0V) with thermal protection at +160°C. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Diodes Incorporated AP2125KS 2 8TRG1 |+| Package | SC-70-5 |+| Category | PMIC |+| Pins | 5 |++## Ordering variants++- `AP2125KS-2.8TRG1`+- `AP2125KS-2.8TRG1K`+- `AP2125KS-2.8TRG1W`++## CAD (KiCad official)++- Symbol: `AP2125KS-2.8TRG1`+- Footprint: `Package_TO_SOT_SMD:SOT-353_SC-70-5`+- 3D model: SC-70-5 (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [Diodes Incorporated AP2125KS 2 8TRG1 datasheet](docs/ap2125ks-2-8trg1-datasheet.pdf) (25 pp, sha256 `73dd4f47f543db12`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
