REF3425IDBVR

Texas Instruments · Voltage Reference · SOT-23-6

REF3425IDBVR from Texas Instruments, in a SOT-23-6. 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 GND_F power_in Ground force connection. Carries the return current for the reference. Tie to the ground plane; use with GND_S in a Kelvin connection to remove voltage drops from the ground return path.
2 GND_S input Ground sense connection. High-impedance sense input that regulates VREF relative to the load's local ground, canceling IR drops in the ground return trace.
3 ENABLE input Enable input. Drive high (VEN ≥ 1.6 V, up to VIN) to enable the reference; drive low (VEN ≤ 0.5 V) to place the device in shutdown (IQ ≈ 2.5 µA typ). Must not exceed IN + 0.3 V. Leakage is ~1 µA typ at VEN = 12 V.
4 IN power_in Input supply voltage. Operating range VREF+VDO to 12 V (absolute max 13 V). Dropout voltage is 50 mV typ at IL = 0 mA. Bypass with a 0.1 µF capacitor close to the pin.
5 OUT_S input Reference voltage output sense connection. High-impedance sense input for Kelvin connection at the load; regulates VREF at the point of load to remove IR drops in the OUT_F trace.
6 OUT_F power_out Reference voltage output force connection. Sources/sinks up to ±10 mA of load current at 2.5 V (REF3425). Requires a stable output capacitor between 0.1 µF and 10 µF.
