# REF6233IDGKR

**Texas Instruments** · Voltage References · VSSOP-8-0.65mm

REF6233IDGKR from Texas Instruments, in a VSSOP-8-0.65mm. 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 REF6233 the supply must be VOUT + 0.25 V minimum to 5.5 V maximum at IOUT = 0 mA. |
| 2 | EN | input | Enable input pin; the enable voltage is specified from 0 V to VIN, with an absolute maximum of VIN + 0.3 V. |
| 3 | SS | input | 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 reference output voltage. |
| 6 | OUT_F | output | Output voltage force pin, which drives the reference output (rated output current ±4 mA for the REF6233). |
| 7 | GND_F | power_in | Ground force pin for the reference output return current. |
| 8 | GND_S | power_in | Ground sense pin for the reference ground connection. |
