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 power input supply (1.2 V to 5.5 V operating). A small 10 µF MLCC should be connected from this pin to GND. Absolute max -0.3 to 6 V. |+| 2 | GND | power_in | Device ground return. |+| 3 | VREFEN | input | Reference voltage input and active-low shutdown control (0.6 V to VCNTL-2.2 V operating; typical 0.9/0.75/0.675/0.6 V). Pulling below ~0.15 V shuts the device off; releasing initiates a ~0.1 ms soft-start. Output VTT tracks VREFEN within ±10 mV. |+| 4 | VOUT | power_out | Regulated termination voltage output; sources and sinks up to ±1.75 A. Requires a minimum 10 µF ceramic capacitor to ground for stability. |+| 5 | NC | unconnected | No connection. |+| 6 | VCNTL | power_in | Control input supply for the internal control circuitry and pass-device drive (3.0 V to 5.5 V operating; typical 3.3 V or 5 V). Must be kept ≥ VIN during power-on/off sequences. Draws ~0.5 mA typical, ~30 µA in shutdown. |+| 7 | NC | unconnected | No connection. |+| 8 | NC | unconnected | No connection. |+| 9 | EP | passive | Exposed thermal pad (PSOP-8 only). Should be connected to the ground copper pour for improved heat dissipation. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Diodes Incorporated |+| Package | ESOP-8 |+| Category | PMIC |+| Pins | 9 |++## Ordering variants++- `AP2303MPTR-G1MTR-G1`+- `AP2303MPTR-G1MPTR-G1`++## CAD (KiCad official)++- Symbol: `AP2303MPTR-G1`+- Footprint: `Package_SO:SOIC-8-1EP_3.9x4.9mm_P1.27mm_EP2.29x3mm`+- 3D model: ESOP-8 (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [Diodes Incorporated datasheet](https://www.diodes.com/assets/Datasheets/AP2303MPTR-G1.pdf) (16 pp, sha256 `e465b64782ac605a`, retrieved 2026-08-17, tier: manufacturer)+- **Extractor:** `ds2sf` (Claude).
