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 threshold 1.15V, hysteresis 140mV) to turn the regulator on; drive below 0.3V to disable it. Leakage is ±0.01µA typical. Do not leave floating. |+| 2 | GND | power_in | Device ground. Connect to a large copper plane to improve thermal performance and long-term reliability. |+| 3 | SW | output | Power switch node output; connects to the drains of the internal P-channel and N-channel MOSFET switches. Connect an external inductor from SW to VOUT. Peak switch current rating 4A. |+| 4 | VIN | power_in | Power supply input, 2.5V to 5.5V operating range (absolute max 6.0V). Must be closely decoupled to GND with a 10µF or greater ceramic capacitor placed close to the pin. |+| 5 | FB | input | Output voltage feedback input. An external resistor divider from VOUT to FB to GND sets the output voltage using the 0.600V internal reference (VOUT = VFB × (R1+R2)/R2). |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | RYCHIP |+| Package | SOT-23-5 |+| Category | PMIC |+| Pins | 5 |++## Ordering variants++- `RY343070301007`++## CAD (KiCad official)++- Symbol: `RY3430`+- 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/ry3430-datasheet.pdf) (10 pp, sha256 `f499af7e71472cb5`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
