**Zynalog** · Voltage Reference · SOT-23-6

ZGR1030AG3 from Zynalog, in a SOT-23-6. 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 | GND_F | power_in | Ground force pin (接地 Force Pin) that carries the reference's ground return current, and it is paired with the GND_S sense pin on the same package. |
| 2 | GND_S | power_in | Ground sense pin (接地 Sense Pin) that provides a separate ground reference for accurate output regulation, and it is paired with the GND_F force pin. |
| 3 | EN | input | Enable pin where VEN = 0 V puts the output in shutdown mode, with the datasheet specifying EN ≥ 2.0 V for operating mode and ≤ 0.3 V for shutdown, and an absolute maximum of Vin + 0.3 V. |
| 4 | VIN | power_in | Input supply voltage pin with a recommended range of Vout + Vdrop to 5.5 V and an absolute maximum of 6 V. |
| 5 | VOUT_S | output | Output sense pin (输出 Sense Pin) that senses the reference output voltage so that the regulated voltage is kept accurate at the load. |
| 6 | VOUT_F | power_out | Output force pin (输出 Force Pin) that delivers the 3.0 V reference output, with a recommended load current of -10 mA to 10 mA and a short-circuit current of 22 to 25 mA. |
