Texas Instruments · Voltage Reference · SC-70-3

REF3325AIDCKR from Texas Instruments, in a SC-70-3. 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 is (VOUT + 0.2 V) to 5.5 V (absolute max 7.5 V). For REF3325 (2.5 V), typical VIN ≥ 2.7 V.
2 OUT power_out Regulated 2.5 V reference output. Sources or sinks up to ±5 mA (recommended), absolute max output short-circuit current 180 mA. Requires a bypass capacitor to GND for stability.
3 GND power_in Ground reference for the device. Connect to the system ground plane.
