BL8555-28PRA from BL Shanghai Belling, in a SOT-23-5. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | VDD | power_in | Input supply pin of the regulator. |
| 2 | GND | power_in | Ground pin. |
| 3 | CE | input | Chip enable pin that switches the regulator on or off (standby mode 0.1uA typ.). |
| 4 | NC | unconnected | No connection. |
| 5 | VOUT | power_out | Regulated output pin (2.8V for this BL8555-28PRA variant, up to 150mA). |
