REF5025AIDGKT 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 | DNC | unconnected | Do not connect; this pin must be left unconnected on the REF50xxAI/REF50xxI VSSOP-8 package. |
| 2 | VIN | power_in | Input supply voltage; for REF5025AI it must be at least VOUT + 0.2V (2.7V minimum applies only to REF5020) and no more than 18V. |
| 3 | TEMP | output | Temperature-dependent voltage output (VTEMP = 509mV + 2.64mV/°C × T) with about 60kΩ source impedance and roughly ±15°C accuracy; low-impedance loads cause measurement error, so buffer it with a low-drift op amp. |
| 4 | GND | power_in | Ground reference for the device. |
| 5 | TRIM/NR | passive | Output trim or noise-reduction pin; a 1µF capacitor from this pin to GND forms a low-pass filter with a 10Hz to 20Hz corner that reduces output noise (at the cost of longer startup time), and the datasheet shows a typical trim of ±15mV using a resistor network. |
| 6 | VOUT | power_out | Reference voltage output (2.5V for REF5025); sources and sinks up to ±10mA, and requires a load capacitor CL of 1µF to 50µF from VOUT to GND with ESR of 1Ω to 1.5Ω recommended. |
| 7 | NC | unconnected | No internal connection; may be left floating or connected to GND. |
| 8 | DNC | unconnected | Do not connect; this pin must be left unconnected on the REF50xxAI/REF50xxI VSSOP-8 package. |
