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 | NC | unconnected | No connection. Leave floating. |+| 2 | GND | power_in | Ground reference for the device. |+| 3 | VOUT | power_out | LDO regulated output voltage (5.0V typ for the -5V variant, 4.9V/5.0V/5.1V min/typ/max). Absolute max -0.3V to 7V. Output current limited to typ 138mA (100-160mA). |+| 4 | VDD | power_in | Voltage input supply / energy storage node. Connect a bulk capacitor from VDD to GND (Cvdd ~= 0.01 * Iload in F) to transfer input energy to the LDO stage. VDD_ON turn-on threshold 7.6/7.8/8V; absolute max 9V. |+| 5 | Drain | power_in | Internal 650V power MOSFET drain. Connect to rectified AC line; provides energy to the backward stage when the input voltage drops into the charging-window interval. Pins 5, 6, 7, 8 are tied together internally to the same drain node - the PCB layout guide directs the user to connect all four pads together and maximize copper area for heat dissipation. |+| 6 | Drain | power_in | Internal 650V power MOSFET drain (paralleled with pins 5, 7, 8). Tie all four Drain pads together on the PCB. |+| 7 | Drain | power_in | Internal 650V power MOSFET drain (paralleled with pins 5, 6, 8). Tie all four Drain pads together on the PCB. |+| 8 | Drain | power_in | Internal 650V power MOSFET drain (paralleled with pins 5, 6, 7). Tie all four Drain pads together on the PCB. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Shanghai Siproin Microelectronics SSP7786A 5 0V |+| Package | SOP-8 |+| Category | PMIC |+| Pins | 8 |++## Ordering variants++- `SSP7786A-5.0VSSP7786A-5V`+- `SSP7786A-5.0VSSP7786A-3.3V`+- `SSP7786A-5.0VSSP7786A-2.7V`++## CAD (KiCad official)++- Symbol: `SSP7786A-5.0V`+- Footprint: `Package_SO:SOIC-8_3.9x4.9mm_P1.27mm`+- 3D model: SOP-8 (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [Shanghai Siproin Microelectronics SSP7786A 5 0V datasheet](docs/ssp7786a-5-0v-datasheet.pdf) (10 pp, sha256 `2afb02d06a43da06`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
