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

RS3433XH6-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; all voltages are specified with respect to the GND pin. |
| 2 | GND_S | power_in | Ground sense connection, used together with the force contacts so that load regulation measurements reflect force and sense contacts. |
| 3 | EN | input | Enable connection that enables or disables the device, with EN range 0 V to IN and a reference active threshold of 1.5 V and shutdown threshold of 0.5 V. |
| 4 | IN | power_in | Input supply voltage connection, recommended from VOUT+0.5 V to 12 V with an absolute maximum of 13 V. |
| 5 | OUT_S | input | Reference voltage output sense connection. |
| 6 | OUT_F | output | Reference voltage output force connection, which must be decoupled with a minimum 1 µF capacitor to GND and is rated for load currents of ±10 mA. |
