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 voltage input. Operating range 1.8V-5.5V, absolute maximum 8V. A 1µF input capacitor (Cin) is recommended. |+| 2 | GND | power_in | Device ground reference. |+| 3 | CE | input | Chip enable input, active-high with no internal pull-down. VCEL ≤ 0.4V shuts the regulator down (ISTANDBY ≤ 0.1µA) and enables the ~250Ω VOUT discharge path; VCEH ≥ 1.5V (up to 5.5V) enables the regulator. Must be tied to VIN or GND - do not leave floating. |+| 4 | NC | unconnected | No internal connection. Leave floating or tie as convenient for layout. |+| 5 | VOUT | power_out | Regulated output voltage (fixed per suffix: 1.2V, 1.8V, 2.5V, 2.8V, 3.0V, or 3.3V for the -33 variant this part → 3.3V). Delivers up to 300mA with 460mV typical dropout at 300mA (Vout=3.3V). Includes foldback short-circuit protection (~60mA into a short) and a ~250Ω active discharge when CE is low. 1µF output capacitor (Cout) recommended. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | BL Shanghai Belling |+| Package | SOT-23-5 |+| Category | PMIC |+| Pins | 5 |++## Ordering variants++- `BL8077CB5TR33CB5TR12`+- `BL8077CB5TR33CB5TR18`+- `BL8077CB5TR33CB5TR25`+- `BL8077CB5TR33CB5TR28`+- `BL8077CB5TR33CB5TR30`+- `BL8077CB5TR33`+- `BL8077CB5TR33CKETR12`+- `BL8077CB5TR33CKETR18`+- `BL8077CB5TR33CKETR25`+- `BL8077CB5TR33CKETR28`+- `BL8077CB5TR33CKETR30`+- `BL8077CB5TR33CKETR33`++## CAD (KiCad official)++- Symbol: `BL8077CB5TR33`+- 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:** [BL Shanghai Belling datasheet](docs/bl8077cb5tr33-datasheet.pdf) (8 pp, sha256 `c075616ed6f58c9f`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
