# RS3430XH6-Q1

**Jiangsu RUNIC Tech** · Voltage Reference · SOT-23-6

RS3430XH6-Q1 from Jiangsu RUNIC Tech, 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 connection; the datasheet states all voltages are referenced to the GND pin. |
| 2 | GND_S | power_in | Ground sense connection, to be routed separately from the force ground for accurate output sensing. |
| 3 | EN | input | Enable input that turns the reference on or off; EN must stay between 0 V and IN, with the reference active above 1.5 V and in shutdown below 0.5 V. |
| 4 | IN | power_in | Input supply voltage; the recommended range is VOUT + 0.5 V to 12 V, with a 4 V minimum supply for VOUT below 4.0 V and an absolute maximum of 13 V. |
| 5 | OUT_S | input | Reference voltage output sense connection, used to sense the output voltage at the load for accuracy. |
| 6 | OUT_F | output | Reference voltage output force connection, sourcing or sinking load current within ±10 mA and rated for a 30 mA output short-circuit current. |
