SGMICRO · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-89-3
SGM2203-5.0YK3G 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 | VOUT | power_out | Regulator output pin; the datasheet recommends an output capacitor of 1μF to 10μF placed very close to this pin. |
| 2 | GND | power_in | Ground pin. |
| 3 | VIN | power_in | Regulator input pin rated up to 36V; the datasheet recommends a 1μF or larger ceramic capacitor from VIN to ground. |
