SGM2019-ADJYN5G 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 | IN | power_in | Input voltage supply pin (2.5V to 5.5V operating range); a 1μF or larger ceramic capacitor from IN to ground is recommended. |
| 2 | GND | power_in | Ground. |
| 3 | EN | input | Enable pin: drive high (above 1.5V) to turn on the regulator and low (below 0.3V) to turn it off. |
| 4 | FB | input | Feedback voltage input pin for the adjustable version; connect to the midpoint of an external resistor divider to set the output voltage (VOUT = (R1+R2)/R2 × 1.207). |
| 5 | OUT | power_out | Regulator output pin (up to 300mA in SOT-23-5); a 1μF or larger ceramic output capacitor located very close to this pin is recommended. |
