SGM2205-5.0XK3G from SGMICRO, in a SOT-89-3. 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 | OUT | power_out | Regulator output pin; the datasheet recommends an output capacitor with effective capacitance of 1μF to 10μF to ensure stability. |
| 2 | GND | power_in | Ground pin. |
| 3 | IN | power_in | Input supply pin with an operating input range of 2.5V to 20V; a 1μF or larger ceramic capacitor from IN to ground is recommended for decoupling. |
