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 | FB | input | Feedback pin. Connect to an external resistor divider from VOUT; internal error amplifier regulates this node to VFB = 0.8V (typ, 0.784-0.816V). VOUT = VFB x (1 + RA/RB), with RB in the 0.7k-5kΩ range. |+| 2 | EN | input | Enable / power-off pin. Logic High (VIH >= 2.0V) enables normal step-down operation; Logic Low (VIL <= 0.8V) stops step-down operation and deactivates all internal circuits. Input leakage typ +20 / -10 uA. |+| 3 | OCSET | input | Over-current setpoint. Add an external resistor to VCC to set the maximum output current threshold. OCSET pin bias current typ 90 uA (75-105 uA). |+| 4 | VCC | power_in | IC power supply pin. Input voltage range 3.6V to 18V (absolute max VSS-0.3 to VSS+20V). Bypass locally with a ceramic capacitor (e.g. 0.1 uF) close to the pin. |+| 5 | Output | output | Switch node output (drain of internal P-channel power MOSFET). Connect the external inductor and freewheeling Schottky diode here. Pins 5 and 6 are internally tied; minimize trace/copper area to reduce EMI. |+| 6 | Output | output | Switch node output (drain of internal P-channel power MOSFET). Connect the external inductor and freewheeling Schottky diode here. Pins 5 and 6 are internally tied; minimize trace/copper area to reduce EMI. |+| 7 | VSS | power_in | Ground return pin. Pins 7 and 8 are internally tied and must both be connected to the PCB ground plane for proper current return and thermal dissipation. |+| 8 | VSS | power_in | Ground return pin. Pins 7 and 8 are internally tied and must both be connected to the PCB ground plane for proper current return and thermal dissipation. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Diodes Incorporated |+| Package | SOP-8 |+| Category | PMIC |+| Pins | 8 |++## Ordering variants++- `AP1534SG-13SG-13`++## CAD (KiCad official)++- Symbol: `AP1534SG-13`+- 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:** [Diodes Incorporated datasheet](https://www.diodes.com/assets/Datasheets/AP1534SG-13.pdf) (11 pp, sha256 `81e2089489abd7a2`, retrieved 2026-08-17, tier: manufacturer)+- **Extractor:** `ds2sf` (Claude).
