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 | LX | output | Power switch output. Drain of the internal N-channel MOSFET switch. Connect the boost inductor and the anode of the output Schottky rectifier here. LX can swing between GND and 30V (absolute max VSW = -0.3V to 30V). |+| 2 | GND | power_in | Ground pin. Return for the internal MOSFET switch and control logic. Connect to a strong ground plane for heat sinking and noise protection. |+| 3 | FB | input | Feedback input. Regulates to VFB = 1.23V (typ, 1.21V-1.25V). Connect an external R1/R2 resistor divider from VOUT to set the output voltage: VOUT = VFB * (1 + R1/R2). FB input bias current is -50nA to -10nA. |+| 4 | EN | input | Regulator on/off control input. VEN threshold ~1V; a high input enables the converter, a low input shuts it down (IIN ~0.1uA at VEN=0V). Absolute max 6V. Tie to VIN for automatic startup when not otherwise used. |+| 5 | IN | power_in | Input supply pin. Operating range 2.5V to 5.5V; absolute max 6V. Must be locally bypassed with a low-ESR ceramic capacitor (22uF X5R/X7R recommended) placed close to the IC. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | RYCHIP |+| Package | SOT-23-5 |+| Category | PMIC |+| Pins | 5 |++## Ordering variants++- `RY375070390005`++## CAD (KiCad official)++- Symbol: `RY3750`+- 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:** [RYCHIP datasheet](docs/ry3750-datasheet.pdf) (7 pp, sha256 `3c00582ad13b7c1a`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
