SCJA1117B-5.0-A from Changjing, in a SOT-89-3L. 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 | Ground reference for the fixed-output SCJA1117B-5.0-A; on the ADJ version this pin is the adjust pin, with IAdj about 50uA per the datasheet, and it is not a supply pin. |
| 2 | OUTPUT | power_out | Regulated output; the datasheet requires a minimum 10uF tantalum capacitor at the output for transient response and stability. |
| 3 | IN | power_in | Unregulated input; the absolute maximum input voltage is 20V and the recommended input voltage is 15V, with a 10uF bypass capacitor recommended. |
