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 | VSS | power_in | Ground / common return for the regulator. All voltages are referenced to this pin. Also labeled GND in the block diagram. |+| 2 | VIN | power_in | Unregulated supply input. Accepts up to 24V continuously (32V abs max). A bypass capacitor should be connected between VIN and VSS, especially for high-impedance sources such as batteries. |+| 3 | VOUT | power_out | Regulated 3.3V output (±2%, VOUT×0.98 to VOUT×1.02). Delivers up to 100mA. Requires a 1-10uF output capacitor to VSS for stability and transient response. Internally short-circuit protected (Iscp ≈ 20mA, Iocp ≈ 120mA). |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | LR |+| Package | SOT-89-3 |+| Category | PMIC |+| Pins | 3 |++## Ordering variants++- `LR7533-M-M`+- `LR7533-M-T`++## CAD (KiCad official)++- Symbol: `LR7533-M`+- Footprint: `Package_TO_SOT_SMD:SOT-89-3`+- 3D model: SOT-89-3 (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [LR datasheet](docs/lr7533-m-datasheet.pdf) (13 pp, sha256 `0b58c65ef75e4ef4`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
