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 | RUN | input | Enable / on-off control input. Drive above 1.5V to turn the converter on, drive below 0.4V to turn it off. Absolute maximum input voltage is -0.3V to +7V. Must not be left floating. |+| 2 | GND | power_in | Device ground return. Connect to the system ground plane; also serves as the low-side reference for the input and output capacitors and the feedback divider. |+| 3 | SWITCH | output | Power switching node output between the internal high-side PMOS and low-side NMOS. Connect to the output inductor (typ. 1uH to 4.7uH). Absolute maximum swing is -0.3V to (VPWR+0.3V); this is a high-current, high dv/dt noise node so keep traces short and wide. |+| 4 | PWR | power_in | Power input supply pin, 2.6V to 6V (absolute maximum +7V, OVP threshold ~7V). Bypass with a 10uF X5R/X7R MLCC placed as close to the pin as possible; provides current to the internal high-side PMOS (RDS(ON) ~200mΩ, current limit 1.8-2.4A). |+| 5 | FBK | input | Feedback input to the internal error amplifier. Connect a resistor divider from VOUT to FBK to GND to set the output voltage; regulated to VREF = 1.13V (1.107V-1.153V). Leakage current is +/-1uA max. Absolute maximum is -0.3V to +7V. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Everanalog IC design |+| Package | SOT-23-5 |+| Category | PMIC |+| Pins | 5 |++## Ordering variants++- `EA8103T5RT5R`++## CAD (KiCad official)++- Symbol: `EA8103T5R`+- Footprint: `Package_TO_SOT_SMD:SOT-23-5`+- 3D model: SOT-23-5 (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [Everanalog IC design datasheet](docs/ea8103t5r-datasheet.pdf) (8 pp, sha256 `a91baf5d66011f05`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
