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 | VDD | power_in | Input supply pin. Operating range 1.4V to 5.25V (absolute max 6.0V). Bypass to GND with ≥1.0µF ceramic capacitor placed as close as possible to the pin. |+| 2 | GND | power_in | Ground reference pin. Provide a low-impedance return trace to minimize noise pickup and dropout error. |+| 3 | CE | input | Chip Enable pin, active HIGH. VCEH ≥ 1.0V enables the regulator; VCEL ≤ 0.4V places the device in standby (Istandby typ 0.1µA). Internal pull-down ~0.3µA (typ). Absolute max 6.0V. |+| 4 | NC | unconnected | No Connection. Pin is not internally bonded; may be left floating or tied to GND for mechanical stability. |+| 5 | VOUT | power_out | Regulated 3.3V output pin (RP114x33xx). Sources up to 300mA continuous. Requires a ≥1.0µF ceramic output capacitor for phase compensation, placed as close to the pin as possible. D-version includes an internal Nch auto-discharge switch (~50Ω) that pulls VOUT to GND when CE is de-asserted. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Ricoh Elec Devices |+| Package | SOT-23-5 |+| Category | PMIC |+| Pins | 5 |++## Ordering variants++- `RP114N331D-TR-FFRP114Nxx1B-TR-FE`+- `RP114N331D-TR-FFRP114Nxx1D-TR-FE`+- `RP114N331D-TR-FF`+- `RP114N331D-TR-FFRP114Kxx1B-TR`+- `RP114N331D-TR-FFRP114Kxx1D-TR`+- `RP114N331D-TR-FFRP114Qxx2B-TR-FE`+- `RP114N331D-TR-FFRP114Qxx2D-TR-FE`++## CAD (KiCad official)++- Symbol: `RP114N331D-TR-FF`+- 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:** [Ricoh Elec Devices datasheet](docs/rp114n331d-tr-ff-datasheet.pdf) (None pp, sha256 `b8b487247a195114`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
