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 | BS | passive | Bootstrap. Positive rail for the high-side switch's gate driver. Connect a 0.01µF capacitor between BS and SW. |+| 2 | VIN | power_in | Input supply, 4.5V to 27V (abs max 30V). Bypass to GND with a low-ESR capacitor placed close to the pin. |+| 3 | SW | power_out | Switch output. Connect to the switching end of the inductor. Abs max -0.3V to Vin+0.3V. |+| 4 | GND | power_in | Ground return. Also tie to the exposed pad on the backside. |+| 5 | FB | input | Feedback input. Regulated to 0.925V (typ). Connect to a resistor divider between Vout and GND to set the output voltage. Abs max -0.3V to 5V. |+| 6 | COMP | passive | Error amplifier compensation node. Connect an RC network to GND for loop stability (see Stability Compensation in the Application Information). Abs max -0.3V to 5V. |+| 7 | EN | input | Enable input. IC turns on when EN > ~2.7V and turns off when EN < ~1.1V; output is discharged when off. Do not float - recommend a 200kΩ pull-up to VIN. Abs max -0.3V to 8V. |+| 8 | SS | passive | Soft-start control input. A capacitor from SS to GND sets the soft-start period (0.1µF ≈ 13ms). Leave unconnected to disable soft-start. Charge current ~6µA. |+| 9 | EP | power_in | Exposed thermal pad on the backside. Must be connected to the GND pin/plane for thermal dissipation. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Diodes Incorporated |+| Package | SOP-8-EP |+| Category | PMIC |+| Pins | 9 |++## Ordering variants++- `LSP5523-R8AR8A`++## CAD (KiCad official)++- Symbol: `LSP5523-R8A`+- Footprint: `Package_SO:SOIC-8_3.9x4.9mm_P1.27mm`+- 3D model: SOP-8-EP (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [Diodes Incorporated datasheet](docs/lsp5523-r8a-datasheet.pdf) (17 pp, sha256 `e680424967a0ff3b`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
