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 | VIN | power_in | Supply input. Operating range 2.2 V to 5.5 V (6 V absolute max). Bypass with a 1 uF ceramic (X7R) capacitor to GND close to the pin for stability. |+| 2 | GND | power_in | Common ground return for the regulator. Serves as the reference for VOUT and EN thresholds. |+| 3 | EN | input | Enable input, active high. VIH >= 1.6 V turns the regulator on; VIL <= 0.6 V (or EN = 0 V) puts the device in shutdown (typ 0.7 uA). Do not leave floating; tie high or drive with a logic signal. Absolute max 6 V. |+| 4 | NC | unconnected | No internal connection. May be left floating or tied to GND. |+| 5 | VOUT | power_out | Regulated output. Fixed 1.8 V for RT9013-18 option, +/-2% accuracy at 10 mA load, 500 mA maximum. Requires only a 1 uF ceramic (X7R) output capacitor for stability. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Richtek Tech |+| Package | SOT-23-5 |+| Category | PMIC |+| Pins | 5 |++## Ordering variants++- `RT9013-18GBB`+- `RT9013-18GBU5`+- `RT9013-18GBY`+- `RT9013-18GBQW`++## CAD (KiCad official)++- Symbol: `RT9013-18GB`+- 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:** [Richtek Tech datasheet](docs/rt9013-18gb-datasheet.pdf) (13 pp, sha256 `15023cfb98e4146e`, retrieved 2026-08-17, tier: manufacturer)+- **Extractor:** `ds2sf` (Claude).
