RS3450XH6-Q1

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

RS3450XH6-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 for the reference, the high-current ground return; the datasheet states no further limit for this pin.
2 GND_S power_in Ground sense connection, the sense-side ground reference for the output; all voltages are specified with respect to the GND pin.
3 EN input Enable connection that enables or disables the device; EN must be at least 1.5 V for active mode and at most 0.5 V for shutdown, with EN rated from 0 to IN.
4 IN power_in Input supply voltage connection; recommended range is VOUT+0.5 V to 12 V, with an absolute maximum of 13 V.
5 OUT_S input Reference voltage output sense connection, used with OUT_F for force and sense regulation of the output voltage.
6 OUT_F output Reference voltage output force connection, which sources or sinks load current of up to ±10 mA.
