**analogysemi** · Voltage Reference · SOT-23-3

REF325SOT233 from analogysemi, in a SOT-23-3. 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 | IN | power_in | Input supply voltage; Table 5 gives a supply range of VOUT + 0.02 V minimum to 5.5 V maximum (REF312 excepted). |
| 2 | OUT | output | Voltage reference output, rated for source and sink output current of ±25 mA per Table 5. |
| 3 | GND | power_in | Ground reference pin for the device. |
