RS3112-1.25XSF3

Jiangsu RUNIC Tech · Voltage Reference · SOT-23

RS3112-1.25XSF3 from Jiangsu RUNIC Tech, in a SOT-23. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 VIN power_in Input supply voltage. Recommended range VOUT+0.3 V to 5.5 V (min 2.45 V for the 1.25 V option). Absolute max 5.5 V. Bypass with 1 uF to 10 uF to GND.
2 OUT output Reference output voltage (1.25 V nominal for RS3112-1.25XSF3). Sinks or sources up to ±10 mA (30 mA short-circuit). Capable of driving 1 uF to 50 uF capacitive loads; 200 us settling to 0.1% with CL=1 uF.
3 GND power_in Ground reference. All voltages are referenced to this pin.
