SGM2211-3.3XN5G from SGMICRO, in a SOT-23-5. 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 | VIN | power_in | Input voltage supply pin; the input range is 2.7V to 20V, and a ceramic capacitor with at least 1.5µF effective capacitance should be connected from VIN to ground for decoupling. |
| 2 | GND | power_in | Ground pin for the regulator. |
| 3 | EN | input | Enable pin: drive high to turn the regulator on and low to turn it off, with precision EN thresholds of VIH 1.120V to 1.295V and VIL 1.050V to 1.195V. |
| 4 | NC | unconnected | No connection on the fixed-voltage version of the device (NC is listed for the fixed version only). |
| 5 | VOUT | power_out | Regulator output pin; a ceramic output capacitor with 1.5µF to 10µF effective capacitance should be placed as close as possible to this pin for stability. |
