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 in the datasheet are referenced to this pin. |+| 2 | VOUT | power_out | Regulated 3.3V output (±2% tolerance). Supplies up to 100mA typical load current (150mA absolute max). Requires an external output capacitor of 1-10uF for stability and transient response. |+| 3 | VIN | power_in | Unregulated input supply. Operates from VOUT+dropout up to 24V (32V absolute max). Requires an external input bypass capacitor, especially with high-impedance sources such as batteries. Dropout is typically 390mV at 50mA and 750mV at 100mA. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | LR |+| Package | SOT-23-3 |+| Category | PMIC |+| Pins | 3 |++## Ordering variants++- `LR7533-TT`+- `LR7533-TM`++## CAD (KiCad official)++- Symbol: `LR7533-T`+- Footprint: `Package_TO_SOT_SMD:SOT-23-3`+- 3D model: SOT-23-3 (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [LR datasheet](docs/lr7533-t-datasheet.pdf) (13 pp, sha256 `0b58c65ef75e4ef4`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
