SGM4027-2.5XN3LG
SGMICRO · Voltage Reference · SOT-23
SGM4027-2.5XN3LG from SGMICRO, in a SOT-23. 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 | Power supply input, which must be operated between (VREF + 0.2V) and 5.5V, with a 0.47μF low-ESR bypass capacitor recommended at this pin for stability. |
| 2 | OUT | output | Reference voltage output, which requires a 2μF to 22μF capacitor and is rated for a maximum load current of 10mA. |
| 3 | GND | power_in | Ground reference pin. |
