REF3025AIDBZR

Texas Instruments · Voltage Reference · SOT-23

REF3025AIDBZR from Texas Instruments, in a SOT-23. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 IN power_in Input supply voltage. Recommended VIN range: VOUT + 0.2V to 5.5V (absolute max 7V to GND). Optional 0.1µF input bypass capacitor.
2 OUT output Reference output voltage (2.5V nominal for REF3025). Load current specified up to 25mA; short-circuit current typ 35mA; stable without an output capacitor (0.1µF to 22µF supported).
3 GND power_in Ground reference for the input supply and output voltage. Common return for all device currents.
