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 | Power supply input, 2.5V to 5.5V operating range (absolute max 6.5V). Must be closely decoupled to GND with a 10µF or greater ceramic capacitor to minimize the CIN/GND loop area. |+| 2 | GND | power_in | Analog ground pin. Maximize PCB copper area on this pin for best thermal and noise performance; a ground plane is highly desirable. |+| 3 | EN | input | Chip enable pin. Drive above VIH=1.5V to turn on the regulator; drive below VIL=0.4V to turn it off. Do not leave floating; input current ~1µA. |+| 4 | FB | input | Output feedback pin. Connect to the center of the output resistor divider (R1/R2) to program Vout = 0.6V * (1 + R1/R2). VREF = 0.6V typical (0.588-0.612V). |+| 5 | LX | output | Power switch output - switch node connecting to the external inductor. This pin ties to the drains of the internal P-ch and N-ch MOSFETs; keep PCB copper area on LX minimized to reduce switching noise. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | TECH PUBLIC |+| Package | SOT-23-5 |+| Category | PMIC |+| Pins | 5 |++## Ordering variants++Same part, different packaging or reel option.++- `AP3428AKTTR-TP`++## CAD (KiCad official)++- Symbol: `AP3428AKTTR-TP`+- 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:** [TECH PUBLIC datasheet](docs/ap3428akttr-tp-datasheet.pdf) (7 pp, sha256 `0f5ba041aa89d6c8`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
