RS3112-4.096XSF3

Jiangsu RUNIC Tech · Voltage Reference · SOT-23

RS3112-4.096XSF3 from Jiangsu RUNIC Tech, in a SOT-23. 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	VIN	power_in	Input supply voltage; absolute maximum 5.5 V with respect to GND, recommended up to 5 V, and must be at least VOUT + 0.3 V (about 4.396 V for the 4.096 V option) to keep the reference in regulation.
2	OUT	output	Reference output voltage (4.096 V for this option) that sources up to 10 mA and sinks up to 10 mA, and requires a minimum 1 µF capacitor from OUT to GND with a capacitive load range of 1 µF to 50 µF.
3	GND	power_in	Ground reference for all voltages; the datasheet states all voltages are measured with respect to the GND pin.
