BCT1117ELT50-TR from BROADCHIP, in a SOT-223-3. 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 | ADJ/GND | power_in | Pin 1 is the adjust pin for the adjustable output option and the ground pin for fixed-output versions, so on the 5.0V fixed part (BCT1117ELT50-TR) it is the ground return. |
| 2 | VOUT | power_out | Output voltage pin for the regulation, rated up to 1A output current; the SOT-223 tab is electrically tied to this pin (Tab is Vout). |
| 3 | VIN | power_in | Input voltage pin for the regulator, with an absolute maximum input of 15V and a recommended maximum of 12V. |
