SGM4027-3.3XN3LG 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; the datasheet specifies operation from (VREF + 0.2V) up to 5.5V, with VIN to GND absolute maximum of 6.0V, and recommends a 0.47µF bypass capacitor at this pin for stability. |
| 2 | OUT | output | Reference voltage output; load current is limited to 10mA (MAX) and a 2µF to 22µF capacitor should be connected at this pin for stability. |
| 3 | GND | power_in | Ground reference for the device. |
