BL Shanghai Belling · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-89-3
BL8078CC3TR33 from BL Shanghai Belling, in a SOT-89-3. 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 | GND | power_in | Ground reference pin for the regulator. Connect to system ground. |
| 2 | VIN | power_in | Supply voltage input. Operating range 3V-40V (absolute max 50V). Requires a 1µF ceramic input capacitor to GND. |
| 3 | VOUT | power_out | Regulated output voltage (3.3V for the -33 suffix). Delivers up to 150mA with 180mA current limit. Requires a 1µF ceramic output capacitor to GND. |
