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 | Unregulated input supply. Operating range 1.2 V to 6 V (absolute max 6 V). Bypass to VSS with a 10 uF ceramic capacitor placed close to the pin. |+| 2 | VSS | power_in | Device ground / return for input and output capacitors. Reference for CE logic thresholds. |+| 3 | CE | input | Active-high chip-enable input. VCEH >= 1.6 V (up to VIN) enables the regulator; VCEL <= 0.5 V (down to 0 V) disables it and drops quiescent current to ~1 uA. Input current 0.5 uA max over VCE=0 V to VIN. Do not leave floating. |+| 4 | NC | unconnected | No internal connection. May be left floating or tied to VSS for improved PCB routing/mechanical stability. |+| 5 | VOUT | power_out | Regulated 3.3 V output (3.24 V min / 3.300 V typ / 3.360 V max at Iout=1 mA, Vin=5 V). Delivers up to 300 mA (Vin=4.3 V). Requires a 10 uF ceramic output capacitor to VSS for stability. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Unknown |+| Package | SOT-23-5 |+| Category | PMIC |+| Pins | 5 |++## Ordering variants++- `RT9193-33GB-MS33GB-MS`++## CAD (KiCad official)++- Symbol: `RT9193-33GB-MS`+- 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:** [Unknown datasheet](docs/rt9193-33gb-ms-datasheet.pdf) (8 pp, sha256 `f30db9087e2ca5f2`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
