# BL8061CC3TR50

**BL(Shanghai Belling)** · Linear Voltage Regulators (LDO) · SOT-89-3

BL8061CC3TR50 from BL(Shanghai Belling), in a SOT-89-3. 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 | GND | power_in | Ground pin of the regulator, connected to the ground return of the input and output capacitors. |
| 2 | Vin | power_in | Input voltage pin accepting 2V to 16V (absolute maximum 20V), recommended to be bypassed with a 1uF ceramic input capacitor. |
| 3 | Vout | power_out | Regulated output pin delivering up to 250mA with ±2% accuracy (±1% customized), recommended to be bypassed with a 1uF ceramic output capacitor. |
