BL8563-12PRA 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 | Vin | power_in | Supply voltage input, operating range 2V to 6V (absolute maximum 8V), with a recommended 1uF input capacitor. |
| 2 | Vss | power_in | Ground pin of the regulator. |
| 3 | CE | input | Chip enable input; high level 1.5V to Vin enables the output, low level 0 to 0.25V shuts down (0.1uA typ.) and engages the 1.5k output discharge resistor, with a 500k internal pull-down. |
| 4 | NC | unconnected | No connection. |
| 5 | Vout | power_out | Regulated output voltage (1.2V for the -12 option), up to 300mA, with a recommended 1uF output capacitor. |
