REF2925AIDBZT

Texas Instruments · Voltage Reference · SOT-23-3

REF2925AIDBZT from Texas Instruments, in a SOT-23-3. 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 IN power_in Input supply voltage; VIN must be at least VREF + 0.05 V and no more than 5.5 V per the recommended operating conditions.
2 OUT output Reference output voltage, which is 2.5 V for the REF2925 per the device comparison table; the device does not require a load capacitor but is stable with any capacitive load.
3 GND power_in Ground reference pin.
