RS3433XH6-Q1

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.
