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 | EN | input | Chip enable input. Drive above 1.5V (typ. rising threshold 1.15V, hysteresis 140mV) to turn the regulator on; drive below 0.3V to shut it down (shutdown current <1µA). Must not be left floating. Absolute max 6.0V. |+| 2 | GND | power_in | Device ground return. Connect to a large copper area to improve thermal performance and provide a low-impedance return for the input capacitor and internal low-side NMOS. |+| 3 | SW | output | Switch-node output; drains of the internal P-channel and N-channel power MOSFETs. Connect to the external inductor. Peak SW sink/source current is rated to 3A; absolute max voltage -0.3V to (VIN+0.3V). |+| 4 | IN | power_in | Power supply input, 2.5V to 5.5V operating (absolute max 6.0V). Must be closely decoupled to GND with a 10µF or greater ceramic capacitor placed near the pin. |+| 5 | FB | input | Output-voltage feedback input. Connect to the external resistor divider tap; the regulator servos FB to the internal 0.600V reference (VOUT = 0.6V x (R1+R2)/R2). Absolute max 6.0V. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | RYCHIP |+| Package | SOT-23-5 |+| Category | PMIC |+| Pins | 5 |++## Ordering variants++- `RY3408`++## CAD (KiCad official)++- Symbol: `RY3408`+- 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/ry3408-datasheet.pdf) (9 pp, sha256 `dff34b6a65435b27`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
