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 | OUT | power_out | Regulated output voltage pin. Adjustable from 1.2V to 90V; requires an output capacitor greater than 2.2 μF for stability. Supplies up to 50 mA with internal short-circuit current limit (typ 120 mA). |+| 2 | FB | input | Feedback pin for the error amplifier. Connect to the tap of the external R1/R2 divider from OUT; regulation forces FB to the 0.8V internal reference (Vout = 0.8V × (R1+R2)/R2). Feedback pin current typ 0.01 μA. |+| 3 | NC | unconnected | No internal connection. Leave floating or tie to GND for best PCB layout. |+| 4 | GND | power_in | Device ground reference. Must be tied to the exposed thermal pad (EP), which shares the GND net and provides the primary thermal path to the PCB. |+| 5 | EN | input | Active-high enable input, CMOS-logic compatible. VENHI ≥ 1.0V enables the regulator; VENLO ≤ 0.4V places the device in shutdown (ISD typ 8 μA). Absolute-max 110V; may be tied to VIN for always-on operation (IEN typ 0.02 μA). |+| 6 | NC | unconnected | No internal connection. Leave floating or tie to GND for best PCB layout. |+| 7 | NC | unconnected | No internal connection. Leave floating or tie to GND for best PCB layout. |+| 8 | IN | power_in | Input supply pin, +7V to +100V operating (abs-max +110V). Requires an input capacitor greater than 0.47 μF (typ 1 μF) placed close to the pin. Dropout is 2.8V at IOUT = 50 mA. |+| EP | GND | power_in | Exposed thermal pad on the bottom of the package, electrically tied to GND. Solder to a copper ground pour on the PCB to conduct heat away from the die. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | GATEMODE |+| Package | MSOP-8-EP |+| Category | PMIC |+| Pins | 9 |++## Ordering variants++- `GM7A4001`+- `GM7A4001S`++## CAD (KiCad official)++- Symbol: `GM7A4001`+- Footprint: `Package_SO:MSOP-8_3x3mm_P0.65mm`+- 3D model: MSOP-8-EP (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [GATEMODE datasheet](docs/gm7a4001-datasheet.pdf) (5 pp, sha256 `9ea341d460e5e0a3`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
