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/ADJ | power_in | Ground / adjust pin. Tie to GND for fixed-voltage operation. In adjustable mode, connect the mid-point of the external resistor divider (R1 to Vout, R2 to GND) here to set Vout = Vref × (1 + R2/R1). Adjust pin current I_ADJ is typically ~2 µA. R1 is normally 1 kΩ-10 kΩ; a 0.1 µF ceramic bypass cap between this pin and GND improves ripple rejection. |+| 2 | VOUT | power_out | Regulated output. Delivers up to 2 A within ±2% of the nominal set voltage (customized 1.2V-5.0V in 0.1V steps; this suffix -33 => 3.3V). A 1 µF ceramic output capacitor to GND is required for stability. Typical dropout is 850 mV at 1.5 A for Vout ≥ 2.0V. |+| 3 | VDD | power_in | Unregulated input supply. Recommended operating range up to 18V (absolute max 20V). Requires a 1 µF ceramic bypass capacitor to GND placed close to the pin. Input must exceed Vout by at least the dropout voltage to maintain regulation. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | BL Shanghai Belling |+| Package | SOT-223-3 |+| Category | PMIC |+| Pins | 3 |++## Ordering variants++- `BL8072CLTR33CLTR`+- `BL8072CLTR33COTR`++## CAD (KiCad official)++- Symbol: `BL8072CLTR33`+- Footprint: `Package_TO_SOT_SMD:SOT-223-3_TabPin2`+- 3D model: SOT-223-3 (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [BL Shanghai Belling datasheet](docs/bl8072cltr33-datasheet.pdf) (7 pp, sha256 `48a7d46f1c8be9ee`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
