RS5050XK

Jiangsu RUNIC Tech · Voltage Reference · SOP-8

RS5050XK from Jiangsu RUNIC Tech, in a SOP-8. 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 DNC unconnected Do not connect; this pin must be left unconnected.
2 VIN power_in Input supply voltage, recommended from VOUT + 0.5 V to 16 V, with an absolute maximum of 18 V (V+ to V-, referenced to GND).
3 NC unconnected No internal connection.
4 GND power_in Ground reference; all voltages are measured with respect to this pin.
5 NC unconnected No internal connection.
6 VOUT output Reference voltage output; load current is limited to ±10 mA, output short-circuit current is limited to ±30 mA absolute maximum, and a minimum 1 µF capacitor must be connected from VOUT to GND (1 µF to 50 µF recommended).
7 NC unconnected No internal connection.
8 DNC unconnected Do not connect; this pin must be left unconnected.
