# REF6250IDGKR

**Texas Instruments** · Voltage Reference · MSOP-8

REF6250IDGKR from Texas Instruments, in a MSOP-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 | VIN | power_in | Supply input voltage pin; for the REF6250 the supply input range is 5.3 V (min) to 5.5 V (max) at IOUT = 0 mA, and the absolute maximum VIN is 6 V. |
| 2 | EN | input | Enable pin; the enable voltage VEN is specified from 0 V to VIN V in the Recommended Operating Conditions, and VEN is limited to VIN + 0.3 V in the absolute maximum ratings. |
| 3 | SS | passive | Short-circuit current limit pin; connect a resistor to this pin to set the output short-circuit current limit, or connect it to VIN for the highest current limit. |
| 4 | FILT | passive | Filter capacitor pin; a capacitor CFILT of at least 1 µF must be connected between FILT and ground for stability. |
| 5 | OUT_S | input | Output voltage sense pin, used to sense the output voltage at the load. |
| 6 | OUT_F | output | Output voltage force pin, which drives the reference output; output current is specified at -3 mA to 3 mA for the REF6250. |
| 7 | GND_F | power_in | Ground force pin, carrying the reference's ground return current. |
| 8 | GND_S | power_in | Ground sense pin, used as the ground reference for sensing. |
