BCT78L05AEUR-TR from BROADCHIP, in a SOT-23. 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 | VOUT | power_out | Output voltage pin for the regulation; the datasheet gives an OUT to GND absolute maximum of -0.3V to 5.5V. |
| 2 | VIN | power_in | Input voltage pin for the regulator; the rated input range is 5.5V to 15.0V, with VIN to GND absolute maximum of -0.3V to 16.0V. |
| 3 | GND | power_in | Ground pin for fixed output. |
