RS3112-3.0XSF3 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 is -0.2 V to 5.5 V with respect to GND, and the recommended input is VOUT + 0.3 V up to 5 V. |
| 2 | OUT | output | Reference output voltage (3.0 V for the RS3112-3.0 option); load current is specified at ±10 mA and a minimum 1 µF output capacitor to GND is required (1 µF to 50 µF recommended). |
| 3 | GND | power_in | Ground reference; all datasheet voltage ratings are referenced to this pin. |
