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 | VOUT | power_out | Regulated LDO output. Factory-set to 2.8V for the -28 suffix (1.0V-3.6V in 0.1V steps for the family). Requires a 1µF ceramic output capacitor to GND for stability; supports up to 750mA (typ. 700mA) with a fast active-discharge path enabled when EN is low. |+| 2 | GND | power_in | Device ground reference. Also connected to the thermal pad on the package underside, which must be soldered to the PCB ground plane for proper heat dissipation. |+| 3 | EN | input | Enable input, active high. Logic high (VIH ≥ 1.2V, up to VIN) turns the regulator on; logic low (VIL ≤ 0.4V) shuts it down (ISHDN < 1µA) and activates the VOUT discharge path. Must not be left floating. Input current ≤ 1µA over 0-5.5V. |+| 4 | VIN | power_in | Unregulated supply input, 2.5V to 6.5V (absolute max 8V). Requires a 1µF ceramic bypass capacitor to GND close to the pin. Dropout is typ. 110mV at IOUT = 200mA. |+| 5 | EP | power_in | Exposed thermal pad on the underside of the DFN1x1-4L package, electrically connected to GND. Must be soldered to the PCB ground copper for thermal performance and mechanical reliability. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Suntek |+| Package | XDFN-4-EP(1x1) |+| Category | PMIC |+| Pins | 5 |++## Ordering variants++- `SK6019AD4-28AD4-XX`+- `SK6019AD4-28`++## CAD (KiCad official)++- Symbol: `SK6019AD4-28`+- Footprint: `Package_DFN_QFN:OnSemi_XDFN4-1EP_1.0x1.0mm_EP0.52x0.52mm`+- 3D model: XDFN-4-EP(1x1) (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [Suntek datasheet](docs/sk6019ad4-28-datasheet.pdf) (8 pp, sha256 `151d8627fd2b92d5`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
