BL8072COTR50 from BL Shanghai Belling, in a TO-252. 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. In fixed-voltage application this pin is tied to GND (0V). In the adjustable configuration it becomes the ADJ feedback node connected to the R1/R2 divider from Vout; the internal reference (VRef) is regulated between Vout and this pin (Vout = VRef*(1+R2/R1) + IAdj*R2, with IAdj ~2uA). A 0.1uF bypass capacitor from ADJ to GND is recommended to improve ripple rejection. |
| 2 | VOUT | power_out | Regulated output voltage pin. Delivers up to 2A with ±2% accuracy (±1% option). For the -50 suffix Vout = 5.0V typical. Requires a 1uF ceramic output capacitor to GND for stability. |
| 3 | VDD | power_in | Input supply pin. Recommended operating input voltage up to 18V, absolute maximum 20V. Requires a 1uF ceramic bypass capacitor to GND. Dropout typical 850mV @ 1.5A for Vout ≥ 2.0V. |
